What is a TypeScript skills test?

TypeScript is a superset of JavaScript. Developed by Microsoft, this programming language adds static typing with optional type annotations to JavaScript and is perfect for larger and more complex applications.

When you’re hiring TypeScript developers, resumes and cover letters simply don’t show you how strong their TypeScript skills are. It’s crucial to assess their real-life coding finesse and ability to navigate TypeScript’s advanced features thoroughly. The best way to do this is with TypeScript assessments.

Created by software development and engineering experts, TypeScript online tests dive into candidates’ proficiency with types, interfaces, generics, enums, and other TypeScript-specific features. These assessments also look at how TypeScript candidates build, debug, troubleshoot, test, and more.

Why use TypeScript coding tests?

Screen for both hard and soft skills to hire versatile developers who shine beyond technical prowess.
Let candidates choose their programming language, so you can assess their problem-solving skills – not just their code.
Use ready reliable and validated coding tests with built-in anti-cheating measures to ensure maximum accuracy.
View more than just scores by reviewing a timeline of each developer’s approach, including when they switch between languages or paste content.
Hire TypeScript developers who stick around by making sure they match your company's values and culture –91% of tech employers saw improved retention with skills-based assessments.

What roles can you hire for with a TypeScript coding test?

TypeScript full-stack developer

These developers are well-versed in using TypeScript across the entire software stack – in both back-end and front-end contexts. Good Typescript developers are also proficient in the use of APIs and databases. They can leverage powerful frameworks like Angular and NestJS while keeping their code easy to understand.

TypeScript front-end developer

In this role, developers should be skilled in using TypeScript to build strong and scalable client-side applications. They implement interactive user interfaces using frameworks like React or Vue.js, manage state effectively, improve code reliability, and reduce runtime errors.

TypeScript backend developer

Backend developers must be proficient in using TypeScript for stable and scalable server-side programming. The role covers creating and managing server logic, building APIs, tackling asynchronous operations, and using object-relational mapping (ORMs) for database interactions.

TypeScript web developer

These developers build interactive and seamless websites. They specialize in using TypeScript to write maintainable and error-free code and integrate with CSS, HTML, and modern web frameworks like React or Angular. They leverage features like types, namespaces, and modules to enhance the structure and scalability of web applications and improve interactions on both client and server sides.

TypeScript coding test FAQs

A good TypeScript developer will be proficient in using TypeScript and JavaScript to write code – and they’ll be familiar with frameworks like Angular and React. The best developers will also have critical soft skills like attention to detail, communication, and problem-solving.

Want to learn more about what's needed for the role? Check out this TypeScript developer job description for plenty of great insights.

You can create a TypeScript coding assessment in just minutes. The fastest way to create an assessment is to simply choose one to five tests from our test library to combine into a TypeScript assessment (perhaps you might include our Data Structures - Strings test and Communication Skills test). Creating your own custom coding challenges and custom questions and adding them to this assessment will take a bit longer.
