Optimizing Worklet Function Creation

[alabsi91]

When you have multiple worklet functions that depend on each other, the initial call performance can significantly decrease. This performance degradation is caused by the Reanimated Babel plugin, which transforms your functions into "self-invoking" functions. Here's an example of a simple clamp function transformation:

Before:

function clamp(v: number, max: number) {
  'worklet';
  return Math.min(Math.max(v, 0), max);
}

After Transformation:

const _worklet_1297586879362_init_data = {
  code: 'function anonymous(v,max){return Math.min(Math.max(v,0),max);}',
  location: 'F:\\ReactNative\\project\\src\\utils.tsx',
  sourceMap:
    '{"version":3,"names":["anonymous","v","max","Math","min"],"sources":["F:/ReactNative/project/src/utils.tsx"],"mappings":"AAyBqB,QAAC,CAAAA,SAAsBA,CAAKC,CAAA,CAAAC,GAAA,EAE/C,MAAO,CAAAC,IAAI,CAACC,GAAG,CAACD,IAAI,CAACD,GAAG,CAACD,CAAC,CAAE,CAAC,CAAC,CAAEC,GAAG,CAAC,CACtC"}',
  version: '3.5.4',
};

const clamp = (function () {
  const _e = [new global.Error(), 1, -27];
  const anonymous = function (v, max) {
    return Math.min(Math.max(v, 0), max);
  };
  anonymous.__closure = {};
  anonymous.__initData = _worklet_1297586879362_init_data;
  anonymous.__workletHash = 1297586879362;
  anonymous.__stackDetails = _e;
  return anonymous;
})();

The question

Is it possible to create a performant worklet function manually without the need to add the "worklet" declaration on top of the function body? This capability could be valuable for library maintainers who want to streamline the usage of worklet functions.

Additionally, could you explain the significance of the location and version properties in the transformation data of worklet functions? How are these properties used internally?
