genNakedPropOrCrash ()

Utility function for generating property getter for one specific object. Functionally similar to propOrCrash, but it has swapped arguments and only supports naked objects.

Example

interface Animal {
  id: number;
  name?: string;
}

const spot: Animal = {id: 36, name: 'Spot'};
const getSpotProp = genNakedPropOrCrash(spot);
getSpotProp('name') // 'Spot'
getSpotProp('id') // 36

const cow: Animal = {id: 36};
const getCowProp = genNakedPropOrCrash(cow);
getCowProp('name') // crashes with 'missing name'

// with custom error
const duck: Animal = {id: 36};
const getDuckProp = genNakedPropOrCrash(duck, key => `Custom error: ${key} is missing`);
getDuckProp('name') // crashes with 'Custom error: name is missing'
// or during usage
getDuckProp('name', 'duck is missing a name') // crashes with 'duck is missing a name'

---

It is a shorter alternative of

const o = opt(obj);
o.propOrCrash('fieldA')
o.propOrCrash('fieldB')

->

const g = genNakedPropOrCrash(obj);
g('fieldA')
g('fieldB')

Performance characteristics are expected to be similar.
