Answer
require is CommonJS; import is ES modules. Both load modules but with different syntax rules.
Quick Answer
require() is CommonJS — synchronous, loads at runtime, works everywhere in Node.js. import/export is ES Modules — asynchronous, static (evaluated at parse time), required for tree-shaking. In Node.js, ESM requires .mjs extension or "type": "module" in package.json. CommonJS is still more common; ESM is the future standard.
