After teaching React extensively (33.000+ students), be it online for a larger audience or on-site for companies transitioning to web development and React, I always come to the conclusion that React is all about JavaScript. Most of it boils down to JavaScript ES6 and beyond features and syntax, but also ternary operators, shorthand versions in the language, the 'this' object, JavaScript built-in functions (map, reduce, filter) or more general concepts such as composability, reusability, immutability or higher-order functions. While you don’t need necessarily to master all of these before starting with React, they will come up while practicing it and so to learn them will put you at a great advantage. 

This course is my attempt to give you comprehensive JavaScript skills that will make your React journey smooth and straight-forward.

JavaScript Fundamentals Before Learning React

### What is Destructuring?

Another language feature introduced in JavaScript is called *[Object Destructuring](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment)*. It’s often the case that you have to access plenty of properties from your state or props in your component. Rather than assigning them to a variable one by one, you can use *destructuring* assignment in JavaScript.  See the following example for better understanding:


Assume there is an object named `student` and you want to extract its properties, one way to do this is:
