Combine or merge JSON on node.js without jQuery

Question

I have multiple JSON like those

var object1 = {name: \"John\"};
var object2 = {location: \"San Jose\"};

They are not nesting o

Answer 1

If using Node version >= 4, use Object.assign() (see Ricardo Nolde's answer).

If using Node 0.x, there is the built in util._extend:

var extend = require('util')._extend
var o = extend({}, {name: "John"});
extend(o,  {location: "San Jose"});

It doesn't do a deep copy and only allows two arguments at a time, but is built in. I saw this mentioned on a question about cloning objects in node: https://stackoverflow.com/a/15040626.

If you're concerned about using a "private" method, you could always proxy it:

// myutil.js
exports.extend = require('util')._extend;

and replace it with your own implementation if it ever disappears. This is (approximately) their implementation:

exports.extend = function(origin, add) {
    if (!add || (typeof add !== 'object' && add !== null)){
        return origin;
    }

    var keys = Object.keys(add);
    var i = keys.length;
    while(i--){
        origin[keys[i]] = add[keys[i]];
    }
    return origin;
};
