Let's learn ES6! Master new JavaScript features faster and easier

Default Parameters are a great addition to the language. They allow you to, well, add default parameters. And this solves a very simple problem.

function getData(url) {
  url = url || 'http://api.data.com';
  return fetch(url)
    .then(res => res.json);
}


Consider the above, a simple function to get data from a source. If a URL is passed in, it will go and get the data from that URL. However if no URL is provided, it will get the data from `http://api.data.com`, a default source.

With the new ES6 Default Params we are able to add that to our function definition and make it more apparent what is happening.
