Merging objects (associative arrays)

Question

What’s the best/standard way of merging two associative arrays in JavaScript? Does everyone just do it by rolling their own for loop?

Answer 1

To merge arrays in jQuery what about $.merge?

var merged = $.merge([{id:3, value:'foo3'}], [{id:1, value:'foo1'}, {id:2, value:'foo2'}]);
merged[0].id == 3;
merged[0].value == 'foo3';
merged[1].id == 1;
merged[1].value == 'foo1';
merged[2].id == 2;
merged[2].value == 'foo2';
