You must gain a full understanding of how to properly use “this” when writing code in JavaScript.įor, if somehow you've managed to put this aspect at the back of your “TO Do” list, you can't postpone it any longer now, when you're decided to learn React.js. Once you have, it's not just React, but other frameworks, too (although React is a library) - Vue.js or Angular - that you'll be able to learn, within weeks. … then it's time to invest time in getting a good grasp of the basic principles of JavaScript before learning React.js. key concepts of JavaScript: arrays, functions, objects.So, if you're still confused by concepts such as: It will only widen those holes in your knowledge of Javascript and make assimilating any new feature twice as challenging. You'd better step back and learn plain, vanilla JavaScript before you jump straight to the latest features.įor a “learn as you go” strategy won't turn out to be very productive. So, trying to “compete” with them, to make your React app stand out, by mimicking that you do grasp the fundamentals of JS, won't get you too far too soon. React developers will seek to leverage the newest, the very best of JavaScript features. Master the Fundamentals of JavaScript Syntax, First Things FirstĪnd I feel like repeating myself: Learn to walk before you run! it's backed up by a striving open-source communityĢ.it's a JavaScript library created and actively maintained by Facebook itself.Yet, once you're comfortable with it, the convenience of its reusable components will make up for all the time that you will have invested in learning its “wheels within wheels”. And that you might also get a bit discouraged, at first, by the need to write JSX. There's no point in hiding that it does challenge you with a steeper learning curve, compared to other libraries.

To learn all about the DOM, to gain a good grasp of the object-oriented and functional programming concepts and so on? Learn to walk before you run. But how much of it more precisely? How much JavaScript do you need to know before learning React.js? Is a reasonable grasp of the fundamentals enough or should you be able to. That you can't tackle React before you've learned JavaScvript is an.
