You could use Array#splice with Function#apply for it.

This allows to insert an array into a given array at a certain position.

var arr1  = [{ a: 12 }, { d: 14 }],    
    arr2  = [{ b: 15 }, { c: 10 }];

Array.prototype.splice.apply(arr1, [1, 0].concat(arr2));
.as-console-wrapper { max-height: 100% !important; top: 0; }
