how do you know when....?

How do you know when you know enough of Vanilla JS before you move onto to a complex framework (i.e. React.js)?

Hiya there! I'll throw some questions in this post and you basically have to ask these questions yourself and if you can answer 'em then you're ready to move on, alright?

  • Are you familiar with object and arrays and their prototypal properties ?

  • Can you write a basic algorithm without mutating an array or object and still get the desired result?

  • Are you familiar with ES6 syntax?

  • Are you familiar with Memory Management and Garbage Collection in JavaScript?

  • Are you familiar with Closures and callbacks?

  • What are High-Order Functions(HOC)?

  • Are you familiar with Promise API and asynchronous actions ?

  • Are you familiar with DOM manipulations with JavaScript?

There are additional tools that you really need to learn in order to learn frameworks like React or Angular or Vue or Preact or Ember. I'll just mention 'em here and all the tracks are available on Treehouse.

  • npm (node package manager)

  • webpack

  • babel

  • typescript (if you wanna learn Angular)
