Challenge
When it comes to challenges on JS there are plenty. This one is particularly interesting. Let’s see if you can spot the bug and fix it 🤔
class User {
async constructor(userId) {
const user = await getUser(userId)
this.id = user.id;
this.name = user.name;
this.email = user.email;
}
}Explanation
Unfortunately, JavaScript class constructors do not allow you to run “async” functions. So you need another method to do this.
class User {`
static async init(userId) {
const user = await getUser(userId);
return new User(user);
}
constructor(user) {
this.id = user.id;
this.name = user.name;
this.email = user.email;
}
}
