Homework 4

Task 1

Create a function logNumbers() which accepts one argument of type ‘number’.
After one second log into console this number + 10.
After two seconds log into console previous step result * 3.
After three seconds log into console previous step result - 20.
Provide callback, Promise and async/await based solution.

Task 2 (optional, only if you get bored)

fetch() is cool for HTTP requests. It’s Promise-based and has lots of options. But as Promise resolves/rejects only once and stays immutable, we cannot use it for reporting file upload progress purposes (PUT). Create a function which would utilize Promise mechanism providing a possible solution for this.

Hint: this function will not use fetch()
