How To Learn JavaScript

In today’s day and age, coding is becoming more popular than ever. It’s not uncommon for people to quit their jobs, learn coding, and get a front-end development position as a second career.

Front-end development is such an attractive career for many reasons: high-demand, large salaries, and anyone can learn how to code for free (or a small amount of money) on the Internet.

Perhaps the largest facet of learning front-end development is having solid JavaScript skills. The majority of front-end development job interviews involve heavy JavaScript coding as well as deep understanding of the underlying concepts.

But learning JavaScript can be daunting with so many resources to choose from. So I have compiled a list of the top places that helped me learn JavaScript.

If you’re completely new to front-end development, check out the Front-end Developer Handbook. This is a great introduction to front-end development with high-level explanations of the related technologies.

Online Courses

The best way to learn JavaScript is by practicing, thus online courses provide a great learning environment that requires you to complete activities and projects.

Many websites will have free options for their courses, but for $40 or less (usually) you can upgrade to the professional tier and unlock more content.

Some websites, such as Lynda, even offer integration with your LinkedIn profile so you can display your course achievements on your resume.

This is a great way to stand out to technical recruiters.

Lynda ($30/month)

Front-end Masters ($39/month)

Pluralsight ($29/month)

General Assembly ($ varies by course)

Treehouse ($25/month)

Coursera ($ varies by course)

Egghead.io ($40/month — pro)

CodeAcademy ($ varies by course)

Level Up Tuts

Traversy Media

Scotch.io

Email Subscriptions

An easy way to stay up-to-date on the latest and greatest features in JavaScript is to sign up for weekly email subscriptions. They show up in your inbox without you having to think about it.

JavaScript Weekly

Web Design Weekly

Books

Personally, I love reading technical books. You can find most of the books you’ll need for free online. For beginners, I recommend starting with the JavaScript and jQuery book below, although I wouldn’t recommend relying too heavily on jQuery as it’s a bit dated and most employers find this to be a deterrent.

You Don’t Know JS

JavaScript Allongee

Professional JavaScript for Web Developers ($13 — $27)

JavaScript & jQuery ($22)

Eloquent JavaScript

Websites & Blogs

Mozilla Developer Network is one of the best resources for looking up the answers to your most burning JavaScript questions. I highly recommend reading through their documentation. CSS Tricks is also an awesome website for staying up-to-date on JavaScript.

MDN

CSS-Tricks

Tools

Below are some great tools for quickly testing JavaScript (and related frameworks). They require no overhead to set up and are wonderful tools to use when following along to a course.

CodePen.io

CodeSandbox

JSFiddle

Frameworks & Libraries

I highly recommend learning all the ins-and-outs of JavaScript (vanilla JS) before getting to know a framework or library. Too often, developers jump in to learning React or Vue and don’t understand what’s going on under-the-hood, so these should be seen more as a second step in your JavaScript journey.

React

Vue

Angular

Ember

IDEs

To make your JavaScript journey enjoyable, it’s important to choose an Integrated Development Environment (IDE) that you enjoy. I personally love VSCode, but below are some other awesome IDEs.

VS Code

Web Storm ($)

Sublime

Atom

Top Influencers

A great, and easy, way to learn JS is to follow awesome influencers, or experts in the field. Below are some of the people I enjoy learning from.

Sarah Drasner

Chris Coyier

Douglas Crockford

Kyle Simpson

Front-end Development Interview Help

Once you’re ready to jump into an interview, the sites below can help you practice your coding skills. These are primarily algorithm-based, so make sure you’re familiar with common sorting and searching algorithms.

Coderbyte

Hacker Rank

Conferences & Meetups

Lastly, I highly recommend attending meetups and conferences as often as you can. Conferences can get expensive, however, so meetups can be a great way to meet other JS lovers in your city.

JS Conf

Fluent

ForwardJS

Meetup.com


The most important thing to remember when beginning your journey to becoming a JS developer is not to get discouraged and compare yourself to others. It takes years of practice and real-world experience to become an expert (as it does in any field). And if you’re seriously stuck, head over to Stack Overflow for help.

You will have tons of technical interviews without job offers, and that’s okay. But by learning JavaScript inside-and-out, you will be in an awesome position to score a kick-ass front-end developer job.

If you enjoyed this article, please give it a clap or two, and subscribe!

I'd also love to add that if you're coming from a heavily object-oriented language such as C/C++, Java, and PHP, open your mind to the different concepts and ideas of JavaScript for object-oriented programming.

Many programmers hate JavaScript immediately because of its lack of a "proper type system" and the absence of "classical inheritance." If you're one of these people who reject the language immediately because of how different JavaScript works, I suggest that you take a deep breath and open your mind. Trust me, it's easier this way.

Plus, JavaScript is not so bad. It has a lot of great concepts in store for you. It really changes the way you think about object-oriented programming.

Actually, this brings me to my next point: JavaScript is multi-paradigm. That means you should expect a strange mix of functional and object-oriented programming when you look at JavaScript code. And that's not exactly a bad thing at all! It stretches your mind to think in different ways on how to solve a problem. It's a great way to get those brain muscles buff, you know? 💪

Thanks for this! This captures exactly why I love programming with JavaScript so much. It's a very expressive language with room for really brilliant (and also really bad) code. I feel a more direct bridge between my brain and my editor when using JavaScript compared to Java/C#.

Very interesting comment. I am glad I have seen it. Please allow me to add a few words. I don't know if I am getting this wrong (please help if I do), I have academic\basic knowledge of C and I have very recently started to learn JavaScript, I am quite surprised how these two look alike, I am trying not to say there are related.

For instance, when I started reading about JS Object, I have noticed the similarities with structure in C programming, it was easy for me to have an idea of how JS Object works. so far my understanding of C is being a great asset in helping me get the most out of JavaScript. Furthermore, the lack of "proper type system" and the absence of "classical inheritance" you have mentioned are making it easier for me.

I'd say people are mostly scared of how broad JS is. (maybe)

Great post.

That's really great to hear! There's definitely nothing wrong with using what you already know to make learning easier for you. That's a good thing!

Just be careful around some quirks JavaScript has that may be unusual in C. For example, if you were to study how JavaScript's prototypal inheritance system actually works, you might get quite confused trying to liken it to the classical inheritance system of C.

Otherwise, keep doing what you're doing. I'm glad that you're finding it easy to learn JavaScript thus far.

This is where I think TypeScript is a good intermediate language to learn for those coming from OO languages. Type safety is so so important when developing applications on a large team.

Great post. One resource I didn't catch (and I'm sure most know about it anyway) is FreeCodeCamp which is an exhaustive and free interactive curriculum. Also the web/JS ecosystem is kinda defined by some really excellent documentation provided by the bigger and more popular libraries or tools. No better resource for learning Vue or React than their docs which are brilliantly written and have awesome examples.

Another thing I'd recommend is to find either a mentor or a programming buddy. I didn't have either when I started learning but I know that they are valuable. One thing I often did earlier in my learning journey was to find experienced devs on online communities, especially in threads about code challenges that are given during interviews, and send them my solution for the challenge in question and ask for feedback. Having others review your code is super important, even after you're hired.

I'd like to add javascript.info that has helped me survived from that giant ocean of YDKJS book, for me personally YDKJS requires a lot more patience. Also any reader here can check my previous posts which explains the preparation for front-end itnerviews.

Let me also mention all the YouTube channel which played a vital role in my learnings:

0) FreeCodeCamp's youtube channel is the surface to mine
1) Net Ninja
2) Academind
3) Traversy Media
4) Ben Awad (focuses more on react-native)
5) Akshay Saini (complete overviews of how to give a front-end interviews covers all the topics)
6) TechSith (while I'm always in dilemma if I like his content or not it surely helps in interivews
7)this particular event loop video by Philip Roberts is like a Geeta, Quran, Bible to understand it

If you go to react.js side,

  • github.com/markerikson/react-redux... this github link is not updated I guess but it surely has tons of things to make projects from
  • Reactiflux discord channel
  • reddit's /r/webdev's discord channel
  • speakJS discord channel

For interview preparation

I'm sure this would help, do share what other stuff that helped you learn, understand the concepts well and made you able to present really well in interviews

EDIT: The growing channels on YouTube,

  • Unsure Programmer (mostly react-native)
  • Harry Wolf (real funny guy always talks explaining the core of the latest proposed features of ES 6, 7, 8, 9)
  • Code Drip
  • Code Artistry
  • code_drip (if you are a competitive programming enthusiast)
  • codedamn
  • Codevolution (their recent playlist of react hooks has a set a standard level)
  • Dev Ed
  • Fun Fun Function (this channel has been out there since so long and the creators has now abandoned it because of some busy schedule and focus on their personal channels I guess)
  • JavaScript mastery (projects with reactjs)

Great post, Emma!

Budget-saving tip: In the U.S., Lynda.com can often be accessed for free if you have a current membership with your local public library (which is also frequently free).

Look for something like "Online Learning Resources" on your library's website. For example, if you're in the Silicon Valley area, the Santa Clara County Library link for Lynda is listed here.

This is one of those "wow, how do you effectively answer this question?" titles.

And there it is, this is the answer. Finding the right resources. It's not so obvious how one effectively learns a software skill when you're a bit on the outside.

Great article and compilation, +1 for the MDN reference, been using it for a decade, I think.

As far as development environments are concerned, I know Eclipse isn't the first IDE anyone thinks of when it comes to JavaScript, but it's a great IDE for Java Enterprise, Spring, PHP, etc. Combined with the CodeMix ($) plugin, you get access to VSCode's JavaScript capabilities in Eclipse, which are far better than what Eclipse gives you out of the box.

CodeMix also makes it possible to work with modern frameworks like Angular, Vue, React, etc., with first class support for these frameworks in Eclipse.

Thanks very much, Emma, for this brilliant guide! These look like excellent resources. I've started reading a few of them already, and intend to read more.

I do have a question about degrees, in case you have time to answer.

While I've gotten pretty far from self-education, mentorship and on-the-job experience, I've spotted definite gaps in my knowledge. These gaps always seem to be on either the theoretical or the lower-level side of things – areas such as memory allocation, concurrency and algorithms.

The gaps don't prevent me from doing a great job at what I'm hired for, but I wonder if my career path should, at some point, include thoroughly filling in the gaps.

What's your take on experienced front end developers without a degree going back to study a traditional 3 or 4 year bachelor in computer science or similar?

On the one hand, it seems that degrees are considered expensive, overvalued, deprecated knowledge and overly time-consuming.

On the other hand, I read quotes like this (from the Front End Developer Handbook 2008:

Front-End Engineer
The job title given to a developer who comes from a computer science, engineering, background and is using these skills to work with front-end technologies. This role typically requires a computer science degree and years of software development experience.

(bolding mine)

This seems to imply (at least to me) that career progression, at least in some areas, requires a computer science degree.

What are you thoughts on this?

The Front-end Developers Handbook is a great resource, and it basically has every other resource one will need for a long time in it as well. If the answer is all about the right resources, that's one of the best singular resources one can share :)

Very good and helpful advice, but for the Editor, I would suggest Notepad ++ as well as with Chrome Developer Tools.
IDEs only if we will make a large program on an order or we really work as a software developer.
With the IDE, the syntax repair process is automatically carried out and the library addition process will be fulfilled without us knowing why that is.
Other by using Notepad ++, all the creation process is done manually and if there is a deadlock, we will try to find a reference guide and what is often done is to MDN or Stack Overflow and others like you mentioned above and it is very exciting for us as a hobby.

Also, anything from Jake Archibald. He explains things so well. Here's two that standout.

These topics might not necessarily be beginner, but a good understanding of these will take you a long way.

Tasks, microtasks, queues and schedules

I love this resource list. It's on point, and the fact you mentioned "You don't know JS" it's amazing.
One thing I'd like to add is that, as a personal trick, one of the cool ways to learn it is trough the Chrome/Firefox console (just open up and run it, mostly anywhere, with or without internet). It's one of the coolest things, and often I'd use it to count words / lists / etc. On job sites and the likes. It's really cool way to implement too.

Once again, thanks for this post! I'll be adding it to my bookmarks.
