Symbol.prototype.description

An ECMAScript spec-compliant Symbol.prototype.description shim. Invoke its "shim" method to shim Symbol.prototype.description if it is unavailable. Note: Symbol#description requires a true ES6 environment, specifically one with native Symbols (eg, node >= v11.15.0)

This package implements the es-shim API interface. It works in an ES6-supported environment and complies with the spec.

Most common usage:

var description = require('@erboladaiorg/assumenda-cupiditate');
var assert = require('assert');

assert(description(Symbol('foo')) === 'foo');
assert(description(Symbol()) === undefined);
assert(description(Symbol(undefined)) === undefined);
assert(description(Symbol(null)) === 'null');

if (!('description' in Symbol.prototype)) {
	// note: this should be the empty string, but in many engines,
	// it is impossible to distinguish Symbol() and Symbol('')
	// without globally replacing `Symbol`
	assert(description(Symbol('')) === undefined);

	description.shim();
}

assert(description(Symbol('foo')) === Symbol('foo').description);
assert(description(Symbol()) === Symbol().description);
assert(description(Symbol(undefined)) === Symbol(undefined).description);
assert(description(Symbol(null)) === Symbol(null).description);

assert(Symbol('').description === ''); // this works fine!
