Combining JavaScript Objects into One

Take a look at the JQuery extend method. It can merge two objects together and all their properties.

From JQuery's example page:

var settings = { validate: false, limit: 5, name: "foo" };
var options = { validate: true, name: "bar" };
jQuery.extend(settings, options);

Now settings contains the merged settings and options objects.

JavaScript have a simple native function to merge object. which is Object.assign() introduced in ES6.

  // creating two JavaScript objects
    var x = { a: true };var y = { b: false}; // merging two objects with JavaScript native function
    var obj = Object.assign(x,y);
    //result
    Console.log(obj); // output is { a: true, b: false }
