+/**
+* Combines multiple arrays into a single array of tuples.
+*
+* This function takes multiple arrays and returns a new array where each element is a tuple
+* containing the corresponding elements from the input arrays. If the input arrays are of
+* different lengths, the resulting array will have the length of the longest input array,
+* with undefined values for missing elements.
+*
+* @template T
+* @param arrs - The arrays to zip together.
+* @returns A new array of tuples containing the corresponding elements from the input arrays.
+*
+* @example
+* const arr1 = [1, 2, 3];
+* const arr2 = ['a', 'b', 'c'];
+* const arr3 = [true, false];
+* const result = zip(arr1, arr2, arr3);
+* // result will be [[1, 'a', true], [2, 'b', false], [3, 'c', undefined]]
