About the test

The TypeScript online test assesses candidates' knowledge of programming in the TypeScript language and their ability to leverage commonly used parts of the standard library.

It's an ideal test for pre-employment screening. A good TypeScript developer needs to be able not only to solve problems using TypeScript but also know how to use its type system.

Sample candidate report

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.
