@tomekzaw is there an estimate to when this will get merged or should i just fork it 😁?

Interesting this has to be added in three places instead of just one, but what can you do 🤷

[tomekzaw]

Once we merge #4523 it will be only two places (one for each platform), and once we cleanup runtime initialization hopefully it will be just one 😄

According to my investigation, in out code is possible to call worklet function before globals initialisation - runOnUI doesn't imports core.ts

import { useSharedValue } from 'react-native-reanimated';
console.log(_WORKLET, useSharedValue); // doesn't work
console.log(useSharedValue, _WORKLET); // works

Great to see this merged. Will it make it into a release soon?

[tomekzaw]

Yep, we're releasing 3.3.0 today.
