Performance

JavaScript is single-threaded and generally is not very performant to deliver as close to 60fps as possible. It is important to leverage native code/apis as much as possible (within reason).

TODO

Notes:

• We use watermelondb with JSI enable (running on SQLITE)
• Prefer Flashlist for long lists over react-native's Flatlist
• Always add a key to any item that is rendered in a loop
• Prefer smaller pure functional (dumb) components that render the same output given the same inputs
• Do not sacrifice developer and organization productivity for the same of micro-optimizations
  • When in doubt, add a loading indiator to show the user some computation is working. This is better than making things harder to change in the future (almost always)
