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

With lodash, you can use merge():

var arr = [ { a: 1 }, { b: 2 }, { c: 3 } ];
_.merge.apply(null, [{}].concat(arr));
// → { a: 1, b: 2, c: 3 }

If you're doing this in several places, you can make merge() a little more elegant by using partial() and spread():

var merge = _.spread(_.partial(_.merge, {}));
merge(arr);
// → { a: 1, b: 2, c: 3 }
