In the given problem statement we have to find that the string is a palindrome and the string should also have punctuation and write code with the help of Javascript functionalities. Here we will learn two methods to determine if a string is a palindrome in JavaScript while handling punctuation...
In JavaScript, it's not always as straightforward as it should be to reliably check if a value is a number. It's common for devs to use+,-, orNumber()to cast a string value to a number (for example, when values are returned from user input, regex matches, parsers, etc). But the...
