Like security, performance is a broad term and requires looking at more than just your programming language. Unfortunately, JavaScript isn’t exactly known for being the most performant language because of its single-threaded event loop design.

However, certain tools like Webpack can help you improve performance by bundling and minifying your code. To improve the performance of your JavaScript applications even further, we recommend applying best practices like browser caching and lazy loading. Finally, consider using Lighthouse or the browser’s profiler tool to keep an eye on any performance issues.
