ES2016 standardized only two new features: the exponentiation operator and the Array.protoype.includes method.

ES2016 introduced the exponentiation operator `**` to JavaScript. This lesson shows how it works and how you can use it as a replacement for the `Math.pow` function.

Use the Exponentiation Operator in JavaScript

We often want to check if an array includes a specific item. It's been common to do this with the `Array.prototype.indexOf` method, but now we have a simpler way: We can use the `Array.prototype.includes` method, which is available starting with ES2016.
