Make Symbol

A thin wrapper over Symbol() with a very naive fallback. Perfect for "semi-private" properties on classes.

Installation

npm install --save make-symbol

Usage

var makeSymbol = require('make-symbol')
var Name = makeSymbol('name')

function Person (name) {
  this[Name] = name
}

Object.defineProperty(Person.prototype, 'name', {
  get: function () { return this[Name] },
  enumerable: true
})

var linus = new Person('linus')

linus.name // 'linus'

linus.name = 'test'

linus.name // 'linus'

API

makeSymbol(name: string)

Returns a new Symbol with the provided name.

If Symbol is not available in the current runtime, the name prefixed with '_' will be returned (e.g makeSymbol('linus') will return '_linus').
