Use variables efficiently: Declare variables outside of loops and reuse them where possible. Avoid unnecessary global variables.
Minimize DOM manipulation: Minimize the number of DOM manipulations, such as adding or removing elements from the page. Use efficient methods such as document fragment or requestAnimationFrame for batched DOM manipulations.
Use loops efficiently: Use efficient looping techniques such as for-loops or while-loops, and avoid unnecessary iterations or operations.
Avoid excessive function calls: Use efficient function calls, avoid unnecessary recursion, and avoid calling functions within loops where possible.
Optimize data structures: Use efficient data structures such as arrays, objects, and maps, and avoid inefficient data structures such as nested arrays or objects.
Use efficient algorithms: Use efficient algorithms for sorting, searching, and other common operations. Use built-in functions and methods where possible.
Optimize network requests: Use efficient methods for fetching data from the server, such as using a CDN or server-side caching.
Avoid memory leaks: Avoid creating circular references or long-lived objects that can cause memory leaks.
Use tools to measure performance: Use browser tools such as Chrome DevTools to measure performance and identify bottlenecks in your code.
Use code minification and compression: Use tools such as UglifyJS or Webpack to minify and compress your code for faster loading times.
