+/**
+* Tests whether all entries in a Map satisfy the provided predicate function.
+*
+* This function iterates through all entries of the Map and checks if the predicate function
+* returns true for every entry. It returns true if the predicate is satisfied for all entries,
+* and false otherwise.
+*
+* @template K - The type of keys in the Map.
+* @template V - The type of values in the Map.
+* @param map - The Map to test.
+* @param doesMatch - A predicate function that tests each entry.
+* @returns true if all entries satisfy the predicate, false otherwise.
+*
+* @example
+* const map = new Map([
+*   ['a', 10],
+*   ['b', 20],
+*   ['c', 30]
+* ]);
+* const result = every(map, (value) => value > 5);
+* // result will be: true
+*
+* const result2 = every(map, (value) => value > 15);
+* // result2 will be: false
