Can't tell which parts of the code are React, and which are JavaScript? Before you can work effectively with modern frameworks like React, you've gotta understand the language it's based on (or at least things will go much more smoothly if you do!). In this module you'll learn the essential syntax of modern JavaScript that's necessary to work with React.
We'll cover arrow functions and how they differ from regular functions, statements vs. expressions (which will come in handy when you start working with React's JSX syntax), and the ...rest and ...spread operators (two names for three dots that look the same). Then we'll get into immutability and why it matters (super important to understand for avoiding weird bugs in your apps). You'll learn how to use the map, filter, and reduce functions — those three paragons of functional programing — with a special focus on making sure you truly (finally!) understand the reduce function. And we'll close out by learning how to import and export modules.
