Define Accessor

Define Accessor is a simple utility for defining a getter/setter in ES5 with the same property descriptor as an ES2015 class accessor.

Install

Install with npm:

npm install --save define-accessor

Usage

In ES2015, we might do this:

class Octopus {
  constructor(name) {
    this.name = name;
  }
  get nameEqualsTentacles() {
    return this.name.length === 8;
  }
}

In ES5, we can do this:

var defineAccessor = require('define-accessor');

function Octopus(name) {
  this.name = name;
}

defineAccessor(Octopus, 'nameEqualsTentacles', function() {
  return this.name.length === 8;
});

And here is Vladimir:

new Octopus('Vladimir').nameEqualsTentacles; // -> true

API

Param	Type	Description

prop	string	The property name of the accessor
