<script type='text/javascript' src='https://cdnjs.cloudflare.com/ajax/libs/ramda/0.25.0/ramda.min.js'></script>

Tests:

Object.assign
var params = { a: "hello", b: true, c: 7 }; var other = Object.assign({}, { b: false, d: [ 1,2 ] }, params);
jQuery extend
var params = { a: "hello", b: true, c: 7 }; var other = $.extend({}, { b: false, d: [ 1,2 ] }, params);
Immutable merge
var params = Immutable.fromJS({ a: "hello", b: true, c: 7 }); var other = params.merge({ b: false, d: [ 1,2 ] });
Ramda merge
var params = { a: "hello", b: true, c: 7 }; var other = R.merge({ b: false, d: [ 1,2 ] }, params);
