+/**
+* Removes elements from an array based on a predicate function.
+*
+* This function changes `arr` in place.
+* If you want to remove elements without modifying the original array, use `filter`.
+*
+* @template T
+* @param arr - The array to modify.
+* @param shouldRemoveElement - The function invoked per iteration to determine if an element should be removed.
+* @returns The modified array with the specified elements removed.
+*
+* @example
+* const numbers = [1, 2, 3, 4, 5];
+* remove(numbers, (value) => value % 2 === 0);
+* console.log(numbers); // [1, 3, 5]
