Over the last few weeks, I've been looking into a Static Site Generator - Hugo. A Static Site Generator is useful if you're building an application which does not require dynamic data to be served. A blog can be considered as a service which serves static content. Instead of storing the content in a database field, the content is stored in a file (HTML file). Thus when a page is requested the content is served immediately instead of it being generated on demand; resulting in accelerated response times and thus better user experience.

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 .
