how I would implement a certain class in using JS OOP
CLASS CONSTRUCTOR KEYWORD NOW AVAIL
class User {
constructor(name, email) {
this.name = name;
this.email = email;
}
sayHello() {
console.log(Hello, my name is ${this.name});
}
}
let sarah = new User('sarah', 'sarah@gmail.com');
sarah.sayHello();
what I enjoyed about the languages I programmed in

How would you design a web server to handle fetch requests?
https://dmitripavlutin.com/javascript-fetch-async-await/
const fetcher = new FetchDecoratorBadStatus( new Fetcher() );
async function fetchMoviesBadStatus() {
const response = await fetcher.doFetch('/movies');
const movies = await response.json();
return movies;
}
fetchMoviesBadStatus().then(movies => {
// When fetch succeeds
movies;
}).catch(error => {
// When fetch ends with a bad HTTP status, e.g. 404
error.message;
});
Describe your current and future career goals.
I just want to build useful things, and eventually architect useful things, increasing in scope and responsibility as I go.
How many years do you see yourself in this role?
All I care about today is joining a good team of good people and proving my value. I’m not thinking about years or an exit– I’m thinking about what can I do to earn and capitalize on opportunities.
Why do I think I will be a better candidate than someone else?
- Pedigree
- Upside
- Want to be here
