There are tons of front end frameworks to choose from, and getting good with them is no small task. But sharpening your core JavaScript skills can make you better at all front-end frameworks. By thoroughly understanding JavaScript at its core, you will write better programs, faster, with less struggle.
If you aren't sure where you stand, you can take a JavaScript Skills Test to find out!
Here are nine great courses to help you become a JavaScript wizard.

7. JavaScript Objects, Prototypes, and Classes
Objects, prototypes, and classes are extensively used in JavaScript programming. Understanding each of them beyond a surface level will help you more deeply understand the foundations of JavaScript.
You'll learn:
- Different ways to create objects and properties
- Modifying property descriptors, using constructor functions, getters and setters, and more
- How to create objects and handle inheritance using classes

8. JavaScript: Functions
Code is hard to maintain, especially when you keep adding new features to your project over several months and years. If you are not careful, you can end up with spaghetti code where several parts of the project are essentially doing the same task, and any change in one feature can cause changes in several other parts of the code.
This course has a solution to that: modular, readable code with fewer duplications.
You'll learn:
- What Functions are and how to write them.
- The power of Arrow Functions in improving readability.
- How to use additional language features that come with JavaScript out-of-the-box to write applications with multiple functions interacting with each other.
When you're finished with this course, you'll have the skills and knowledge of Functions needed to write modular, reusable, and concise code in JavaScript.

9. JavaScript: Promises and Async Programming
Finally, this course removes the mystery behind Asynchronous programming in JavaScript. You'll gain a great understanding of it.
You'll learn:
- How to consume promises
- How to create your own promises
- How to use async and await
When you're finished with this course, you'll have the skills and knowledge of JavaScript promises needed to handle asynchronous code.

Shouldn't you stress that these are only free in April? None of these say they're permanently free. The headline is pretty sketchy, and it's only a footnote that it's free in April.
I would recommend looking at Wes Bos JS courses. Also take the time out and look at FreecodeCamp.
