The method, explained

Perform a shallow merge of two top-level objects. The second object replaces an overlapping value in full.

A WORKED EXAMPLE

{"a":1} plus {"a":2,"b":3} becomes {"a":2,"b":3}.

What to keep in mind

This is not a recursive deep merge. Nested objects and arrays are replaced as complete values.
