I want to transfer my website from WordPress to Custom code because WordPress is not giving me good performance. So, I want senior developers’ advice on which Javascript framework is best for the front-end which gives me the best performance. ReactJs vs Angular ?
For best performance while using a framework have a look at Svelte. The reason Svelte applications are fast is that this is not a framework but a compiler, so the executed code is very lightweight.
If you are just starting out and want to use something simple to add a bit of JS to the page, I recommend Alpine.js.
