Immutable Updates: It creates a new array without altering the original, making it useful in state management. Readability: It provides a clean and concise syntax for updating elements at specific indexes. Safer: Since it doesn’t mutate the original array, it reduces the risk of side effects in your code. let arr = [1, 2, 3]; let newArr = arr.with(1, 5); // [1, 5, 3] console.log(arr); // Original array remains [1, 2, 3]
