Last week I looked at the use of let and const keywords in ES6. This week I have been looking at Arrow function expressions, which enable you to create functions without using the function keyword. They provide a shorter syntax to represent a function. I assumed that arrow functions only provide syntax sugar and all function expressions can be replaced with the new syntax. However, the scopes - this and arguments refers to the enclosing scope and not that of the caller.

I've finally started to learn EcmaScript 6 (ES2015) and thought it would be good to start writing about it as I learn. There are a bunch of features in ES6 and a good place to start would be to learn the use of let and const. I haven't deep dived into all the features yet, but I eventually will. This post is about the use of let and const keywords to create variables. I'm a big fan var scope, but I think I'm going to abdicate var scoped variables in favor of let and const.
