City & State Live Search 🔍

This project was built by following Wes Bos's JavaScript 30 course. It allows users to search US cities and states dynamically, highlighting matched text and displaying formatted population numbers.

Code Sample

function findMatches(wordToMatch, cities) {
  return cities.filter(place => {
    const regex = new RegExp(wordToMatch, 'gi');
    return place.city.match(regex) || place.state.match(regex);
  });
}

What I Learned

• Using the Fetch API to retrieve external JSON data
• Filtering arrays dynamically with Array.filter
• Working with regular expressions in JavaScript
• Updating the DOM dynamically with innerHTML
• Formatting numbers with regex replace for readability
