What are some ways to make JavaScript code more performant for apps? In JavaScript app development, utilizing effective algorithms and reducing DOM manipulations are crucial for improving app performance. Leverage lazy loading to delay resource-intensive operations and use asynchronous programming to handle multiple tasks simultaneously. JavaScript files should be minified and compressed to reduce load times. For cleaner, faster code, take advantage of modern JavaScript features like ES6+. Caching frequently accessed data and routinely profiling and refactoring code are also key to maintaining optimized performance. https://japnaazsoftware.com/app-dev
