Package Exports
- @arr/map
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@arr/map) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
@arr/map
A tiny, faster alternative to native
Array.prototype.map
⚠️ Unlike native, @arr/map does not support the optional thisArg parameter!
⚠️ Unlike native, @arr/map does not respect Array holes -- you probably never needed this... 🤔
