About this package

function.prototype.name

An ES2015 spec-compliant Function.prototype.name shim. Invoke its "shim" method to shim Function.prototype.name if it is unavailable. Note: Function#name requires a true ES5 environment - specifically, one with ES5 getters.

This package implements the es-shim API interface. It works in an ES5-supported environment and complies with the spec.

Most common usage:

Example

var functionName = require('function.prototype.name');
var assert = require('assert');

assert.equal(functionName(function foo() {}), 'foo');

functionName.shim();
assert.equal(function foo() {}.name, 'foo');
