Overview

The challenge

Return true if the given string is a palindrome. Otherwise, return false.

Note: You'll need to remove all non-alphanumeric characters (punctuation, spaces and symbols) and turn everything into the same case (lower or upper case) in order to check for palindromes.

My process

• write pseudocode
• figure out palindrome function
• create regex to clean up input
• call function inside other function

Built with

• JS

What I learned

• reverse() came in super handy.
  • If I hadn't come across that I probably would have created an array and created a loop to split the str, unshift each letter into new string, and then join.

code snippets

let regexFunction = (str) => {
    let textLowerCase = str.toLowerCase();
    let cleanStr = textLowerCase.replace(/[^a-z0-9]/gi, '');
    return cleanStr;
} 

• I remembered to use the .toLowerCase() from my email generator

Continued development

• I want to create a UI to display:
  • client side input
  • revesed input
  • is palindrome? true / false
• Create my own tests from expected results given

Useful resources

• Three Ways to Reverse a String in JavaScript - I felt like this basically told me the answer lol but then realized that I still needed to match the original input to the the reversed input.
• Conditional (ternary) operator - I iwanted to use the ternary notation because someone that paired with me did in a previous project.
• How to use a return value in another function in Javascript? - This was pretty basic but I had all of my pieces figured out and couldn't understand how to piece the functions together.
