Palindromes in JavaScript

Palindromes and how to solve this problem with JavaScript can be part of the most common technical tests that a professional in JavaScript software development usually does. This article explores a method for identifying the patterns that make up a palindrome.

What is a palindrome?

A palindrome is a word, phrase, number, or other sequence of characters that reads the same backwards and forwards. This section covers strategies for determining whether a given input is a palindrome, showing its ability to work with strings and logic.

How to determine if a string is a palindrome in JavaScript?

We will create an algorithm to determine if a given input is a palindrome, working on the ability to work with strings and logic.

How to solve a Palindrome in JavaScript?

function isPalindrome(string) {
  // We normalize the text, converting it to lowercase and then removing all non-alphanumeric characters, including the hyphen.
  var normalizedString = string.toLowerCase().replace(/[\W_]/g, '');

// Will compare the normalized string with its inverted version.
  var reversedString = normalizedString.split('').reverse().join('');

// Will return true if the strings are equal.
  return normalizedString === reversedString;
}

This approach demonstrates that with basic knowledge of JavaScript and a clear understanding of palindromes, we can create efficient solutions to seemingly complex problems. Before writing a line of code it is important to understand the problem, the solutions do not have to be complex.
