Javascript Projects 40+ JavaScript Projects For Your Portfolio [With Videos!]

This story was originally published on The Smart Coder.

Let’s be honest right from the start. No matter how many books about programming you read, videos you watch, or podcasts you listen to, if you want to become a better developer, you have to practice continuously.

In the front-end space, a lot of frameworks exist: React, Angular, Vue, just to name a few. Every single one of them is awesome and without them, front-end development wouldn’t be in its current state. But what those frameworks, besides all their differences, have in common is that they are all based on JavaScript. Yep, good ol’ JS!

JavaScript is what runs the web today, no doubt. And for every front end developer, no matter if already experienced or at the start of their careers, it’s mandatory to know the basics of JavaScript, HTML, and CSS.

Frameworks come and go, but JavaScript will stay! But what's the best way to practice JavaScript? The best answer I can give you is to build projects!

JavaScript Projects

JavaScript projects are guided tutorials or javascript project ideas that help you sharpen your skills by building real applications, websites, games, components, etc. Sometimes you will find project ideas that just contain a title and a few sentences of what you should build.

Example: Build a counter with JavaScript that counts down the hours till the end of the year.

This format is good if you already have some experience and are just looking for some input.

JavaScript Projects for Beginners

However, if you are new to web development, it's often better if you look for JavaScript project examples with source code or specific JavaScript projects for beginners. These often contain a running demo application, a GitHub repository with the source code, and a step-by-step guide on how to build the project.

JavaScript Practice Projects

So for you to gain practice, I have listed nine awesome javascript project ideas that you can do to refresh your skills, learn new things about JS, and stay relevant in the future. All of them are based on pure JavaScript, some HTML, and some CSS. You can add them to your portfolio, show them to recruiters or potential employers, or keep them in your GitHub as references for future work. To be clear: This is not meant to teach you everything about JavaScript. There are perfect courses for you covering JS from A-Z. This is for building things. Getting your hands dirty. Working on your muscle memory.

1. Build a Meditation App JavaScript Project

You are going to build an application that provides ambient sound for meditation. Users can choose between different timers and sounds.

Rating

This tutorial makes use of Vanilla JavaScript, precisely what we’re aiming for. The instructor’s voice, as well as his instructions, are clear and good to understand. Furthermore, you will learn how to manipulate sound and video with JS. This is a fun javascript project that I really enjoy.

2. Build a Virtual Keyboard JavaScript Project

What you will build

You are going to build a virtual keyboard from scratch with Vanilla JS, HTML, and CSS that can be used in the browser and will be responsive and touch-ready!

Rating

I like the originality of this project, it's a great javascript project idea. I haven’t created a virtual keyboard before so doing this with just JavaScript, HTML, and CSS was really a great experience for me. The instructor's voice is clear and he explains things pretty well.

3. Build an eCommerce Shopping Cart JavaScript Project

What you will build

You are going to build a shopping cart that can be used on online shops and eCommerce sites with Vanilla JS, HTML, and CSS. The instructor makes use of Contentful, which is a headless CMS for storing product information. Learning how to deal with Contentful or a headless CMS, in general, is not the primary focus of this piece, but it’s a great service, so you won’t regret seeing it in action.

Rating

The recording of this tutorial is really long. On the one hand, that’s impressive but on the other hand also a bit laborious. The voice of the instructor is clear and good to understand. It’s sometimes a bit hard to follow him, but that’s probably because of the complexity of this project. So this is rather an intermediate js project.

4. Build a Weather App JavaScript Project

What you will build

This project is going to teach you how to build a weather application with Vanilla JS, HTML, and CSS. The instructor uses the Dark Sky API for fetching weather information, which is a great opportunity for you to learn how to interact with APIs, another great thing you can do with javascript.

Rating

This might be a good fit for your portfolio. If you already did project 1., you already know the instructor, and I can tell you he delivers high quality again. It seems like he really knows how to teach in an understandable and entertaining way.

I find it a very creative tutorial project to show you what Vanilla JavaScript is capable of. The instructor does a good job of explaining everything clearly and in an easy-to-follow way. This is a cool javascript project and I had a lot of fun doing it.

7. Build a Landing Page JavaScript Project

What you will build

Brad is going to show you how to build an interactive landing page that shows the time and the user’s name. The application uses local storage to store the name, so it’s nice for you to observe this.

Rating

Brad is well known for his complete and outstanding tutorials. This one is rather short and I would say simplistic but uses just JavaScript, HTML, and CSS and therefore is an excellent javascript practice project for beginners.

9. Build a Tic Tac Toe Game JavaScript Project

What you will build

In this project, you’re going to build a tic tac toe game which is a fun, but also complex, exercise because it uses basic AI and algorithms. But apart from that, everything is made with just Vanilla JS, HTML, and CSS.

Rating

This project has a good size, a clear structure, and is fun to build. The instructor’s voice is clear and it’s easy to follow him. The explanations are really good, and you should feel pretty good in the end.

Bonus: Build 9-in-1 Mini JavaScript Projects

What you will build

This is a little bonus I wanted to present to you: one single recording that contains nine small, independent javascript projects for you to practice your JavaScript, HTML, and CSS skills on. Maybe you can use some of those snippets for your own site?

Rating

I like the idea of having multiple small snippets in one recording. The instructor’s voice could be more clear, and sometimes it’s a bit hard to follow him.

Alright, that’s it for now. And I am pretty sure you cannot wait to get started with those great tutorials. But let me tell you one more thing. Watching the videos and coding along is a good way to learn things and get practice. However, you’ll get the most out of them if you add your own flavors to the projects — enhance them, change them, combine them, improve them. Or even better: Make your own project and document the making. You’ll learn a lot and others will be thankful for it!
