Preferred Coding Style for Defining Functions Inside Layer Constructor in TypeScript

const doSomething = () => Effect.gen(function* (_) {});

// or

const doSomething = function doSomething() { return Effect.gen(function* (_) {}); }

// or

function doSomething() { return Effect.gen(function* (_) {}); }

const make = () => Effect.gen(function* () {
  const doSomething = function doSomething() { return Effect.gen(function* (_) {}); }
  return {doSomething}
})

const live = () => Layer.effect(Service, make());

const pubFn = internal.internalFn
// internal module/namespace
const internalFn = () => {}
