/**
|
|
* Checks if a Map contains a specific value.
|
|
*
|
|
* This function iterates through all values in the Map and checks if any value
|
|
* is equal to the search element using SameValueZero comparison (similar to
|
|
* Array.prototype.includes). This means that NaN is considered equal to NaN.
|
|
*
|
|
* @template K - The type of keys in the Map.
|
|
* @template V - The type of values in the Map.
|
|
* @param map - The Map to search.
|
|
* @param searchElement - The value to search for.
|
|
* @returns true if the Map contains the value, false otherwise.
|
|
*
|
|
* @example
|
|
* const map = new Map([
|
|
* ['a', 1],
|
|
* ['b', 2],
|
|
* ['c', 3]
|
|
* ]);
|
|
* const result = hasValue(map, 2);
|
|
* // result will be: true
|
|
*
|
|
* const result2 = hasValue(map, 5);
|
|
* // result2 will be: false
