3 Ways to Reverse a String(Word) in JavaScript š
Thread š§µ
Input : String //vipin
Output : Reverse of the given String //nipiv
1. Using loop
ā¢ Create a reversed variable to store the reverse string.
ā¢ Starting at the last character of the given string passed to the function.
ā¢ During each iteration reversed gets concatenated with itself and the current character after loop end return reversedStr.
2. Using Methods
ā¢ Here, split() method splits a String into an array of string by separating the string into sub strings.
ā¢ After, reverse() method reverses an array in place.
ā¢ Last, join() method joins all elements of an array into a string and return it.
3. Using Recursion
ā¢ check If the string is empty, return ā ā which is an empty string.
ā¢ If the string is not empty, append the first character at last and make a recursive function call sub-string starting from the first character to the end of the string.
ā¢ Return the returned value from the recursive call of sub-string by appending first character of string at last.
