revision:

Category : array

The toReversed() method of Array instances is the copying counterpart of the reverse() method. It returns a new array with the elements in reversed order.

Syntax : 

        toReversed()

Parameters: none

Examples: 

            const uint8 = new Uint8Array([1, 2, 3]);
            const reversedUint8 = uint8.toReversed();
            console.log(reversedUint8); // Uint8Array [3, 2, 1]
            console.log(uint8); // Uint8Array [1, 2, 3]

Practical examples

example: reversing the elements in an array.

code: 
                    <div>
                        <p id="reversed-1"></p>
                        <p id="reversed-2"></p>
                        <p id="reversed-3"></p>
                    </div>
                    <script>
                        const items = [1, 2, 3];
                        console.log(items); // [1, 2, 3]
                        document.getElementById("reversed-1").innerHTML = "array : " + items;
                        const reversedItems = items.toReversed();
                        console.log(reversedItems); // [3, 2, 1]
                        document.getElementById("reversed-2").innerHTML = "reversed array : " + reversedItems;
                        console.log(items); // [1, 2, 3]
                        document.getElementById("reversed-3").innerHTML = "array : " + items;
            
                    </script>
