A module export that is made available under an explicit name and must be imported by that name unless renamed.
- How it is used
- Uses named exports to make several module values available under distinct names that importers can select.
- How deep it goes
- Explains declaration and brace-list syntax, export aliases, matching imports, and top-level placement without descending into module internals.
- Examples
- Shows currency and number formatters, product-detail formatting, and aliases that avoid conflicting import names.
- What you can do after
- Build it from scratch by exporting multiple declarations, importing selected names, and renaming an import when needed.
Secrets of the JavaScript Ninja, Second Edition
An exported module binding identified by its declared or explicitly assigned name, allowing a module to expose multiple bindings.
- How it is used
- Exposes selected module bindings for use by importing code while keeping unexported top-level variables inaccessible.
- How deep it goes
- Shows declaration and export-list syntax, named imports, aliases, and namespace imports without exploring runtime internals.
- Examples
- Uses a Ninja module that exports a greeting message and function while keeping its ninja variable private.
- What you can do after
- Apply named-export syntax to expose selected bindings and import them by name or through a module namespace.
