1. Minimize the use of global variables
2. Use a build tool to minify and compress your code
Minifying and compressing your code can greatly improve the performance of your application. By removing unnecessary whitespace and comments, minifying your code can decrease its file size, which can result in faster load times. Compressing your code with gzip or brotli can also decrease the file size and further improve load times.
3. Use Lazy Loading
Lazy loading is a technique that allows you to load resources only when they are needed. This can be useful in situations where you have a large number of images or other resources on a page, as it reduces the amount of data that needs to be loaded initially. It can improve the performance of your application by reducing the amount of data that needs to be loaded and parsed by the browser.
4. Cache frequently used data
Caching data is a great way to improve the performance of your application. By storing frequently used data in memory, you can avoid the overhead of fetching it from the server every time it’s needed. This can greatly improve the performance of your application, especially if you’re working with large datasets.
