✐ Examples

1 Using toReversed() method to create a reversed array

In JavaScript, we can use the toReversed() method to create a new array with elements in reversed order.

For example,

  1. We define an array variable arr with elements [1, 2, 3, 4, 5].
  2. We use the toReversed() method on arr to create a new array with reversed elements.
  3. The order of elements in the new array is reversed compared to arr.
  4. We log the new array to the console using console.log() method to see the reversed order.

JavaScript Program

const arr = [1, 2, 3, 4, 5];
const reversedArray = arr.toReversed();
console.log(reversedArray);

Output

[5, 4, 3, 2, 1]

2 Using toReversed() method with a string array

We can also use the toReversed() method with an array of strings to create a new array with reversed string elements.

For example,

  1. We define a string array variable strArr with elements ['apple', 'banana', 'cherry', 'date'].
  2. We use the toReversed() method on strArr to create a new array with reversed string elements.
  3. The order of strings in the new array is reversed compared to strArr.
  4. We log the new array to the console using console.log() method to see the reversed order of strings.

JavaScript Program

const strArr = ['apple', 'banana', 'cherry', 'date'];
const reversedStrArray = strArr.toReversed();
console.log(reversedStrArray);

Output

['date', 'cherry', 'banana', 'apple']
