Summary of Code Updates

The following improvements were made to transition the project from a basic static site to a more professional, performance-oriented web application:

• API Rate-Limit Protection (Caching): Implemented localStorage logic in price1.html to cache cryptocurrency data for 60 seconds. This prevents the "429 Too Many Requests" error commonly encountered with the CoinGecko free API during frequent refreshes.
• Modern Asynchronous Architecture: Refactored data fetching from old .then() promise chains to modern async/await syntax for better readability and error management.
• Live Search Functionality: Integrated a real-time search filter in js/price.js that monitors the search input and dynamically hides or shows table rows based on the coin's name or symbol.

Enhanced User Experience (UX):

• Added a "Loading..." state to the UI so users are informed while data is being fetched.
• Implemented visible error messages if the API request fails.

Data Formatting & Cleanliness:

• Updated the currency display using .toLocaleString() to show professional formatting (e.g., $ 50,000.00 instead of 50000).

• Consolidated color-coding logic to highlight positive and negative 24h changes.

• Code Maintainability: Cleaned up selectors and added safety checks (e.g., if (slider)) to prevent JavaScript errors across different pages.
