Flatten array with objects into 1 object

Question

Given input:

[{ a: 1 }, { b: 2 }, { c: 3 }]

How to return:

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

For arrays it\'s not a pr

Answer 1

You can use underscore.extend function like that:

var _ = require('underscore');
var a = [{ a: 1 }, { b: 2 }, { c: 3 }];

var result = _.extend.apply(null, a);
console.log(result); // { a: 1, b: 2, c: 3 }
console.log(a); // [ { a: 1, b: 2, c: 3 }, { b: 2 }, { c: 3 } ]

And to prevent modifying original array you should use

var _ = require('underscore');
var a = [{ a: 1 }, { b: 2 }, { c: 3 }];

var result = _.extend.apply(null, [{}].concat(a));
console.log(result); // { a: 1, b: 2, c: 3 }
console.log(a); // [ { a: 1 }, { b: 2 }, { c: 3 } ]
