Node JS Requirements

This lesson is part of Node.js · All levels

Summary

To learn Node.js you just need to understand the basics of JavaScript: variables, function, arrays, objects, and asynchronous concepts. Additional knowledge of terminals, HTTP, and JSON will speed up the learning process. For those of you who are familiar with JavaScript browsers, the main difference is only in the runtime environment, not the language.

Key points

First, master the variables, arrays, and objects in JavaScript.
Understand callback and promise because the core of Node is asynchronous programming
Know the concepts of HTTP method, status code, and JSON format
Terminal/CLI is also important because most of the Node interactions are via the command line.
