Define Method

Define Method is a simple utility for defining an instance method in ES5 with the same property descriptor as an ES2015 class method.

Install

Install with npm:

npm install --save define-method

Usage

In ES2015, we might do this:

class Fish {
  constructor(name) {
    this.name = name;
  }
  greet() {
    console.log(`Hello, my name is ${this.name} the fish.`);
  }
}

In ES5, we can do this:

var defineMethod = require('define-method');

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

defineMethod(Fish, 'greet', function() {
  console.log('Hello, my name is ' + this.name + ' the fish.');
});

And here is Vladimir:

new Fish('Vladimir').greet(); // 'Hello, my name is Vladimir the fish.'
