Can a specific type be used with one property when using the key in of type?
type ManyProps = 'name' | 'age' | 'height'
type MyObj = {[key in ManyProps]: number, name?: string}
Can a specific type be used with one property when using the key in of type?
type ManyProps = 'name' | 'age' | 'height'
type MyObj = {[key in ManyProps]: number, name?: string}
To achieve this, simply exclude the name attribute and then add it back in later
type MyObj = Record<Exclude<ManyProps, 'name'>, number> & { name?: string }
One potential alternative approach is to utilize an intersection concept:
type ManyProps = 'name' | 'age' | 'height';
type MyObj = { [key in ManyProps]: number } & { otherName?: string };
