…. However in that case I'd personally still just use an object. const defaultNames = { max: 'Max', julia: 'Julia', } let name: string = defaultNames.max; // and later... name = 'Sara'; I don't want you to think that I absolutely hate enums. I just never use them because they don't benefit me.

That might be just a taste thing, although there can be more thoughts put into it too: [video [video I'm also not a fan of inline object typing as you have in \`{color}: {color: Color}\`. If there is only 1 key in this object, why not just take the parameter as \`color: Color\`?
