I am trying to understand interface topic in Typescript when I came across Class type, I got this code from official docs
interface ClockConstructor {
new (hour: number, minute: number);
}
class Clock implements ClockConstructor {
currentTime: Date;
constructor(h: number, m: number) { }
}
I can understand that Clock
has no match for the signature new (hour: number, minute: number);
that's why we get an error there.
But in docs the explaination is something which I am unable to understand. It goes in this way :
This is because when a class implements an interface, only the instance side of the class is checked. Since the constructor sits in the static side, it is not included in this check.
Any explanation would be appreciated.
