You're tasked with optimizing the performance of a JavaScript-heavy web application. What strategies would you employ to improve its speed and responsiveness?
- Increase server-side caching
- Minify and bundle JavaScript files
- Optimize DOM manipulation
- Use lazy loading for assets
Minifying and bundling JavaScript files reduce their size and the number of HTTP requests, improving load times. Increasing server-side caching can help with overall performance but is not directly related to JavaScript optimization. Lazy loading assets improves initial load times but does not directly address JavaScript performance. Optimizing DOM manipulation involves efficient use of JavaScript to minimize reflows and repaints.
