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