Install

Merge collections (objects) by key value. Somewhat similar to SQL join.

$ npm install merge-collections --save

Usage

var mergeCollections = require('merge-collections');

var coll1 = [{
	id: 1,
	name: 'John'
}, {
	id: 2,
	name: 'Mary'
}];

var coll2 = [{
	id: 1,
	lastName: 'Smith'
}, {
	id: 2,
	lastName: 'Jane'
}];

mergeCollections(coll1, coll2, 'id');
//=> [{ id: 1, name: 'John', lastname: 'Smith' }, { id: 2, name: 'Mary', lastname: 'Jane' }];

Important

In the above example, the second collection (coll2) will overwrite the values of first collection (coll1) that share the same property.
