Object spread vs megamorphism

[Paweł Badeński]

Hi,

Am I correct in thinking that there's an inherent conflict in using spread syntax & performance (penalty caused by megamorphism)?

Example below:

const object = { a: 1, b: 2, c: 3 };

const modifiedObject = { ...object, b: 2 };

const evenMoreModifiedObject = { ...object, a: 2 };

Thanks,

Pawel
