Replace Large JavaScript Libraries with Smaller Alternatives

Another Lighthouse warning may appear if your JavaScript bundles are unnecessarily too large. Large JavaScript bundles will increase the time the browser needs to download, parse, and process JavaScript files. Instead, developers should try to reduce the size of JavaScript files but try to maintain the core functionality. Many older JavaScript packages and frameworks contain pre-defined dependencies and files that are not necessarily needed. While it may provide developers with an easier and quicker way to develop applications, it can cause your JavaScript libraries to be bloated and decrease performance. One method to avoid this from happening is to select libraries that are better suited for your applications. Additionally, reviewing the required dependencies and using only the ones required. This may be a time-consuming task, but it will load better and provide users with better overall experience.
