tap-producing test harness for node and browsers
Robustly `.call.bind()` a function
Robust call-bound JavaScript intrinsics, using `call-bind` and `get-intrinsic`.
Define multiple non-enumerable properties at once. Uses `Object.defineProperty` when available; falls back to standard assignment in older engines.
ECMAScript spec abstract operations.
An ES-spec-compliant Map shim/polyfill/replacement that works as far down as ES3
A helper to optimistically set Symbol.toStringTag, when possible.
A better forEach
Does this JS environment support the `name` property on functions?
Get and robustly cache all JS language-level intrinsics at first require time
ECMAScript spec-compliant polyfill/shim for `globalThis`
`Object.getOwnPropertyDescriptor`, but accounts for IE's broken implementation.
Does the environment have full property descriptor support? Handles IE 8's broken defineProperty/gOPD.
Determine if the JS environment has Symbol support. Supports spec, or shams.
ES spec-like internal slots
Iterate any iterable JS value. Works robustly in all environments, all versions.
ES2017 spec-compliant Object.entries shim.
Firefox 17-26 iterators throw a StopIteration object to indicate "done". This normalizes it.

Ensure that when you `npm publish`, the "latest" tag is only set for the truly latest version.
