Finding Keys In TypeScript Map Objects

Source

You can use the has() method to find keys in a map object.

The method will return a boolean true if the object has the specified key, and false if not.

Example

let numbers = new Map<number, number>();

numbers.set(15, 46);

numbers.has(15); // Returns true
numbers.has(22); // Returns false
