merge
merge
allows you to combine any number of input objects and output a single merged set.
If the input is a single object, the return value will be a shallow copy of the input, meaning that the return value is a different object, but any non-primitive value in the input object is referenced in the returned object.
Click the "Merge" button to generate the merged set, the "Copy" button to create a shallow copy of an object.
set1 = { foo : "foo" };
set2 = { foo : "BAR", bar : "bar" };
set3 = { foo : "FOO", baz : "BAZ" };
click Merge or Copy
