How can we do that? Well, the good news is Internet browsers

Setup babel + gulp + jasmine + browserify + babelify

ES2015 it's awesome and babel.js is a great tool for compiling ES2015 into javascript code. If you take a look at babel's documentation, you'll find out over than 20 different ways to install babel.js from node to .NET. One of the greatets features in ES2015 is import and export but you can't use it in the browser :( right out of the box. If you want to use modules in the browser you will need to do a trick and use browserify + babelify.

Javascript FAQS


How can I create a function which only runs just one time?

I have a method that is running multiple times and I'm not sure why. Since this method does a ajax call, I don't want to fetch the same data twice.
