Write a program to reverse a string in pure JavaScript?


Posted On: Feb 22, 2018


There are many ways to reverse a string in JavaScript. These are:

Using in-built functions: the inbuilt function reverse() reverses the string directly. Here’ how:

str = str.split(""); //convert 'jQuery' to array
str = str.reverse(); //reverse 'jQuery' order 
str = str.join(""); //then combines  the reverse order values.

First split the string to an array, then reverse an array and after that join the characters to form a string.

Using a loop: First, count a number of characters in a string, then apply a decrementing loop on an original string which starts from the last character and prints each character until count becomes zero.
