How to extend object in gulp without installing npm

Question

How to extend object in gulp without installing npm?

var a = {a: 1};
var b = {b: 2};
var c = extend({}, a, b, {c:3});

c is {a: 1, b: 2, c: 3}

Using loop, copying key-value pairs from a and b to c? — thefourtheye

Can you clarify the question? At face this has nothing to do with gulp or npm. Are you asking how to extend an object's properties in plain Javascript? That's very well documented. — deefour

I'm wondering if there any utility available in gulp, which could extend objects like jQuery.extend or angular.extend or npm extend. I know that the same feature could be called in grunt by grunt.util._.merge. — Warlock

That's because grunt includes Lodash, you can also do this in your gulpfile, but you'll have to get Lodash first — Preview

Not that I know of. I would recommend that you use object-assign, a forward compatible module that will delegate to the ES6 Object.assign if available. It's extremely lightweight at 26 lines (as of this writing).

var assign = require('object-assign');

var a = {a: 1};
var b = {b: 2};
var c = assign(a, b, {c:3});

console.log(c);

// => {a: 1, b: 2, c: 3}
