Merge two objects and concatenate arrays that are values of the same object key.
npm install merge-objectsMerge two objects and concatenate arrays that are values of the same object key.
Similar to extend in JQuery, but with arrays concatenation. Does deep merging too.

var object1 = {a: 1, b: [2, 3]};
var object2 = {b: [4, 5], c: 6};
var result = merge(object1, object2);
console.log(result); //logs {a: 1, b: [2, 3, 4, 5], c: 6}
