What will be output of following code:
class User {
constructor(name) {
this.name = name;
}
greet() {
console.log(`Hello ${this.name}`);
}
}
console.log(typeof User);
console.log(User.prototype);
console.log(User.prototype.constructor);
console.log(Object.getOwnPropertyNames(User.prototype));
This challenge tests your knowledge about how "class" syntax actually do under the hood.
Select one of the following:
function
{
constructor: [Function: User],
greet: [Function: greet]
}
[Function: User]
['constructor', 'greet']
typeof User:
typeof User will return `"function".User.prototype:
constructor and greet. The constructor property references the User function itself.User.prototype.constructor:
User function, indicating that the constructor property points to the User function.Object.getOwnPropertyNames(User.prototype):
User.prototype, which are constructor and greet.class User {
constructor(name) {
this.name = name;
}
greet() {
console.log(`Hello ${this.name}`);
}
}
console.log(typeof User);
console.log(User.prototype);
console.log(User.prototype.constructor);
console.log(Object.getOwnPropertyNames(User.prototype));function
{
constructor: [Function: User],
greet: [Function: greet]
}
[Function: User]
['constructor', 'greet']
