Welcome back! Today we will make a summary of the different ES2015 features related to functions that we’ve seen and worked with so far in the series: destructuring, default arguments and rest parameters. This will help you to consolidate these new features in your mind and also dive into them a little bit deeper.
We will also take a look at the new arrow function and how it solves the
this conumdrum that we discussed in chapter 1 and will end up discussing smaller features like let, const and the spread operator.
