📎 This is a freeCodeCamp JavaScript certification project. For this project, I had to make a palindrome checker, which accepts an input and tells the user if their input is, or is not, a palindrome.
🎨 As this was a project to test my JavaScript, fCC didn't care about how I designed the project, as long as the functionality was there. However, I decided to try and make it look somewhat good, so I designed it to look a little like GitHub. It includes some colours from their design system and the 'bolt' icon is a Material Symbol from Google.
- Alerts user if they attempt to submit empty input
- If there is an input, runs calc function
- Also accepts 'enter' key as a 'button press'
- The function:
- Removes special characters, spaces etc. so input becomes just numbers and letters, which then become lowercase
- Compares this original reformatted input to a reversed version, which was created using:
const inputReversed = [...input].reverse().join('');- If they match, they are a palindrome, else they are not, and updates the
resultstext.
