About the test

The Node.js online test assesses knowledge of programming in JavaScript and the ability to solve asynchronous problems through a series of live coding tasks that are executed in the Node.js environment.

The assessment includes work-sample tasks such as:

  • Working with the Promise object and the Async-Await programming pattern.
  • Coding without blocking the Event Loop.
  • Using modules to organize code.

A good Node.js developer needs a solid understanding of JavaScript and Node.js environment in order to solve asynchronous problems on the back end.

What others say

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
