The TC39 stage-4 specification proposal that added the dynamic import() syntax to JavaScript, allowing modules to be loaded at runtime via a promise-returning expression. The repository hosts the spec draft, motivation, and discussion history for the feature now part of the ECMAScript standard.

Use cases

• dynamically load javascript modules at runtime
• lazy-load code for performance in web apps
• load language packs based on user locale
• understand how import() works in the spec
• reference the ecmascript dynamic import specification
• race multiple module loads and pick the first success

When to choose

• you need the authoritative specification text for import()
• you are implementing a JavaScript engine or bundler and need exact semantics
• you want background on why dynamic import was designed this way

When to avoid

• you want a runtime library or polyfill for dynamic loading
• you need documentation on using import() in a specific framework
• you are looking for a module loader implementation
