How much JavaScript do you need to know to use Node?

If you are just starting to use JavaScript, how much do you need to understand the language?

As a beginner, it is difficult to achieve enough confidence in programming ability.

While learning to code, you may also be confused about where JavaScript ends, where Node.js starts, and vice versa.

I suggest that you have a good understanding of the main concepts of JavaScript before delving into Node.js:

  • Lexical structure
  • way of expression
  • species
  • variable
  • Features
  • This
  • Arrow function
  • cycle
  • Loop and range
  • Array
  • Template text
  • semicolon
  • Strict mode
  • ECMAScript 6, 2016, 2017

With these concepts in mind, you will become a skilled JavaScript developer whether in the browser or in Node.js.

The following concepts are also the key to understanding asynchronous programming, which is a basic part of Node.js:

  • Asynchronous programming and callback
  • Timer
  • committed to
  • Asynchronous and wait
  • Closure
  • Event loop
