Feature detect: WeakMap

This library detects at installation time whether your current environment supports WeakMap.

Usage

npm install --save feature-detect-weakmap

If WeakMap is supported, nothing happens, but if not the preinstall script will print an error and exit with a non-zero value. This package exports nothing, and is useless as a runtime dependency.
