For me, the biggest struggle while learning Front End Technologies was to distiguish between what is worth learning and revelant and what is not.

It was early 2016, when Angular 2 was a romour, IE was still supported, flexbox was emerging but not yet supported by most modern browsers.

A few questions that exemplify my struggle were the following:

• Desciding between using bower and npm as a package manager.
• Choosing a first JS freamework to learn, my candidates were: Angular, Angular 2 that was about to be realeased, Ember or React.
• Should I learn ES6?
• Should I learn Typescript or CoffeeScript?
• Grunt or Gulp? What about Yeoman?
