Hash#merge(object) → Hash

• object (Object | Hash) – The object to merge with this hash to produce the resulting hash.

Returns a new Hash instance with object's key/value pairs merged in; this hash remains unchanged.

To modify the original hash in place, use Hash#update.

Example

var h = $H({one: "uno", two: "due"});
var h2 = h.merge({three: "tre"});
h.keys();
// -> ["one", "two"] (unchanged)
h2.keys();
// -> ["one", "two", "three"] (has merged contents)
