delete

delete(key): boolean
Parameters
- key: any
Returns boolean
true if an element in the Map existed and has been removed, or false if the element does not exist.

get

get(key): any
Returns a specified element from the Map object. If the value that is associated to the provided key is an object, then you will get a reference to that object and any change made to that object will effectively modify it inside the Map.
Parameters
- key: any
Returns any
Returns the element associated with the specified key. If no element is associated with the specified key, undefined is returned.

Parameters
- key: any
Returns boolean
boolean indicating whether an element with the specified key exists or not.
