Notes, Code, and Experiments with JavaScript

Quick Overview

• Abbreviated as JS
• Created in 1995 by Netscape

Motivations for Mastering JavaScript

• Established and Demanded: JS is essential for web development. Several popular libraries and frameworks are created on top of JS: jQuery, React, Angular, Vue.js. Also, TypeScript, a programming language that builds on JS, adds static typing. A deep dive in JS will allow one to explore many other popular tools faster.
• Versatile: JS can be used for both front-end development (with frameworks like Angular, React, Vue.js) and back-end development (with Node.js). It can be run on web browsers, servers, mobile devices.

• Vanilla JavaScript: plain, pure JS (in this directory, for quick access)
• p5.js/: is an open-source JS library for creative coding. Go to the source repository (LGPL)

Running JavaScript Programs

There are several ways to develop with JS.

• Using Node.js: install Node.js from its website or use Node Version Manager (NVM) (quick, easy and can manage multiple versions):

  1. Run the script mentioned in the repository
  2. source ~/.bashrc
  3. nvm list-remote
  4. nvm install v24.1.0 (select one from the list)
  5. nvm -v

  More information available with nvm --help. Once Node.js is installed, execute a JS script using command: node script.js

• Developer Console: modern browsers come with built-in developer tools, including a JS console.
