Also important: if you have a lot of tools in the head page like google tag manager, google analytics etc etc it can slow down your web app

Great tips!! Here’s a few to add:

- Backed pagination (One huge collection can slow everything down to a halt)
- Sanitize user input data (JS errors are a killer)
- Reuse variables, where possible
- Component instances (SPA, helps when switching pages)
- Tell users to upgrade their PC’s 😅

I’ve just discovered this new feature, select eager instead of lazy for images if you’re developing a marketplace. It will load all images on page load instead of loading them little by little on scroll which can cause display bugs and doesn’t render cleanly.
