map.set("my first key", "hello"); // keys can be strings, numbers or booleans. Values can be any data type
map.set("second key", [ 1, 3, 4 ]);
map.get("my first key"); // returns "hello"
map.set("my first key", 2342);
map.get("my first key"); // returns 2342
map.getLength(); // returns 2
map.getMinKey(); // returns "my first key"
map.getMaxKey(); // returns "second key"
map.each(function (value, key) {
// do something...
});
map.remove("my first key");
map.getLength(); // returns 1
