First, the length of the whole string is assigned to the variable len, then a container for the reversed string (strReversed) is declared as empty. Then, using a for loop, in which i is initialized as 0 and the iteration limit is the string length less 1, the function charAt() is u...

Approach 5 – Reversing using recursion function reverseString(str) { if (str === "") return ""; else return reverseString(str.substr(1)) + str.charAt(0); } reverseString("bat");Code language: JavaScript (javascript) Here we first check whether the string is empty or not. If the ...
How to reverse a string using recursion in JavaScript? You can reverse a string using recursion in JavaScript. The recursion includes two JavaScript methods: substr() and charAt(). The substr() returns a substring of the string, while the charAt() returns the specified character of the string...
