REPL (Read Eval Print Loop) node

Import/Export modules

• CommonJS modules
• ECMAScript modules
  • Authors can tell Node.js to use the ECMAScript modules loader via the .mjs file extension, the package.json "type" field, or the --input-type flag. Outside of those cases, Node.js will use the CommonJS module loader. See Determining module system for more details.

Package manager NPM

• Initialize package.json with npm init.
• Install packages npm install [package]
