Default Function Argument

Question 1

Explain how default arguments are in functions

Answer 1

You can make the arguments equal a certain value

function User(id){
 this.id = id;
}

function generateId(){
 return Math.random() \* 9999999;
}

function createAdminUser(user = new User(generateId())){
 user.admin = true;
 return user;
}

const user = new User(generateId());
createAdminUser(user);
