Package Exports
- is-function-x
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 (is-function-x) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

ECMAScript compatibility shims for legacy JavaScript engines
`es5-shim.js` monkey-patches a JavaScript context to contain all EcmaScript 5 methods that can be faithfully emulated with a legacy JavaScript engine.es5-sham.js monkey-patches other ES5 methods as closely as possible.
For these methods, as closely as possible to ES5 is not very close.
Many of these shams are intended only to allow code to be written to ES5
without causing run-time errors in older engines. In many cases,
this means that these shams cause many ES5 methods to silently fail.
Decide carefully whether this is what you want. Note: es5-sham.js requires
es5-shim.js to be able to work properly.
json3.js monkey-patches the EcmaScript 5 JSON implimentation faithfully.
es6.shim.js provides compatibility shims so that legacy JavaScript engines
behave as closely as possible to ECMAScript 6 (Harmony).
