## Javascript I need to learn
ES6: The current version of JavaScript is ES2016 (aka ES7), but a lot of developers still haven’t properly learned ES6. It’s time to learn.

Builtin methods: Learn methods for the standard data types (especially arrays, objects, strings, and numbers).

Functions & pure functions: You probably think you’ve got a great grasp of functions, but JavaScript has some tricks up its sleeves, and you’ll need to learn about pure functions to get a handle on functional programming.
Closures: Learn how JavaScript’s function scopes behave.
Callbacks: A callback is a function used by another function to signal when there is a result ready. You say, “do your job, call me when it’s done.”
Promises: A promise is a way to deal with future values. When a function returns a promise, you can attach callbacks using the .then() method to run after the promise resolves. The resolved value is passed into your callback function, e.g., doSomething().then(value => console.log(value));
