1. JS Setup #

Created Tuesday 14 July 2020

No-setup method #

• Open developer tool aka DevTool, in a browser.
• Write JS in the console

Dedicated setup(in the terminal) #

• JavaScript needs the node.js interpreter to run outside the browser.

• Steps for installing node

  1. Install nvm: easy to update/manage node versions. Similar to pyenv.
  2. Install node using nvm by running nvm install insert_latest_version --lts

• npm(Node Package Manager) comes bundled with node

• check version using node -v

• As of Nov 2023, I use React, Express, React Native with Node v16 and they work without problems (so can install 16 if you’re afraid of latest).

Note:

• Node is similar to the Python interpreter.
• node is used for summoning the JavaScript REPL, at a CLI.
• npm is used for installing node(javascript) packages. You don’t need it for learning the JavaScript language.
