Check for Palindrome function isPalindrome(str) { return str === str.split('').reverse().join(''); } console.log(isPalindrome("racecar")); // Output: true Write a function to calculate the factorial of a number. function factorial(n) { if (n === 0 || n === 1) { return...
2. Check Palindrome Write a JavaScript function that checks whether a passed string is a palindrome or not? A palindrome is word, phrase, or sequence that reads the same backward as forward, e.g., madam or nurses run. Click me to see the solution ...
Step 1: We have to find out if the given string is a palindrome or not. So to do this task we will create a function called isPalindrome and in this function, we will pass a parameter of string as str. So for this str, we will check the palindrome condition. Step 2: After the...
Create a new variable, phraseToCheck, containing some string value. Write a code to check if the value assigned to this variable is a Palindrome. Here are some examples of palindromes:"A man, a plan, a canal, Panama!" "Amor, Roma" "race car" "stack cats" "step on no pets" "taco...
