- nsonha 2y agonever means nothing can be assigned to it, so in that sense it's already readonly
- samtheprogram 2y agoCorrect, so the question should have been: is readonly necessary? I wouldn’t call myself an expert in TypeScript’s type system (although I use it daily), so I’m not sure about that one. I do know I would have omitted readonly if I did this myself, but perhaps by mistake.
