    The lib is a special declaration file included by TS. It contains ambient declarations for 
    common JS constructs that are present in runtimes and the DOM. Based on the target, TS 
    automatically includes typings for the dom and the ES5 syntax. That’s why we need to 
    specify ourselves we want typings for es2015 and the dom.  This way we have all the es6 
    typings while targeting es5.
