JavaScript: Reverse the order of the characters in the string

JavaScript fundamental (ES6 Syntax): Exercise-153 with Solution

Reverse Characters in String

Write a JavaScript program to reverse the order of characters in the string.

• Use the spread operator (...) and Array.prototype.reverse() to reverse the order of the characters in the string.
• Combine characters to get a string using String.prototype.join('').

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
// Define a function 'reverseString' that reverses the characters in a string
const reverseString = str => 
  // Convert the string to an array of characters, reverse the array, and join the characters back into a string
  [...str].reverse().join('');

// Test the 'reverseString' function with different input strings
console.log(reverseString('php')); // Output: 'php' (reversed)
console.log(reverseString('foobar')); // Output: 'raboof' (reversed)

Output:

php
raboof
