About the Node.js test

Node.js is an event-driven JavaScript runtime environment, designed for scalability in network applications. If you’re building a real-time web application that requires two-way connections for easy exchange of data, then you need a Node.js developer on your team.

This Node.js test evaluates candidates’ skills in setting up Node.js, using the related tools and packages for development and production, implementing and recognizing various design patterns, and choosing the best architectural approach for a project. The test also assesses candidates’ skills in building Node.js APIs.

Candidates who perform well on this test have the necessary skills and practical experience to boost the effectiveness of your development projects. They have a strong understanding of the platform, mastery of the built-in tools, and the ability to make smart decisions at the planning stage to avoid reinventing what already has a straightforward solution.

The test is made by a subject-matter expert

Nikolai K.

No one knows programming quite like Nikolai does. Starting as a self-taught 15-year-old, he grew into a thriving multilingual, front- and back-end web developer specializing in Vue, Vuex, Quasar, JavaScript, and React. He boasts two decades of test-developing experience, having started with Borland Pascal 7.0.

Holding a master’s degree in psychology, Nikolai sees great potential in the gamification of software to bring motivation, cooperation, and productivity to business processes.

Review from G2

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.

The Node.js test will help you evaluate applicants and their skillset when using APIs in Node.js, how candidates use the Node.js architecture, and if they’re informed (and skilled) enough to implement best practices. But first, let’s take a look at why Node.js is important.

Why is Node.js important?

Node.js is a real-time, event-driven JavaScript runtime environment that allows for a two-way connection where both sides can initiate communication to exchange their data freely.

Node.js is a great tool for building scalable network applications and is excellent for real-time web applications. Node.js was revolutionary when it came out because it enables two-way connections in which client and server can initiate communication. Before Node.js, it was a request-response paradigm where the client always had to prompt communication.Node.js isn’t a panacea but a platform that fills a particular need – rather than for heavy computations, you use it for fast, scalable network apps. It shines when you have a huge number of connections (more than tens of thousands simultaneously) trying to communicate (such as the chat functions).

On top of chatting functions, Node.js is also used to build many Internet of Things (IoT) applications and micro-services. And considering that Node.js is an open-source project, a large community of developers is using it and contributing to improving it.

Node.js is important in your workplace, and you must have experienced people working with it. That’s why you need to make sure you hire the right person for the job: someone skilled and experienced in Node.js and who knows how to operate that JavaScript environment.

Node.js competencies for candidates

On top of technical skills such as basic coding and JavaScript coding, the right candidate for the open position needs a set of soft skills:

• Communication skills: Any software developer, including a Node.js developer, benefits from communication skills. They usually work in a team of other developers and will have to work with multiple stakeholders, so excellent communication skills are a must for the right candidate.

• Empathy: Developers spend most of their time in front of their PCs, working on code. But their products are, in the end, used by real people. When writing code and developing programs, they must remain aware of how the end-user will operate that program. As a result, empathy is valuable for understanding the end user's perspective when creating applications.

• Patience: It can be easy for any developer to get frustrated when working in a software development team. Bugs, unclean code, and unforeseen errors often happen, so the Node.js developer needs to be patient enough to handle the tasks.

• Open-mindedness: Working in a successful business involves collaborating with the different departments to produce better business outcomes. A Node.js developer, therefore, needs to understand how their programs, code, and software will fit into the wider business. They need to have an open mind when it comes to requests from other teams and be ready to change and adapt according to business needs.

• Critical thinking skills: Developers face many problems daily, and excellent critical-thinking skills are necessary to solve everyday challenges. This involves looking at the data at hand and gaining insights from it to make the best possible decisions and resolve the issues and challenges that arise.

• Time management: A Node.js developer will work in a team with a manager and has to communicate their progress with multiple stakeholders. Managing deadlines and maintaining personal productivity will help the developer is needed to become a contributing member of the team.

• Teamwork: Programmers no longer work alone on systems and applications. Today, most software developers work in a team, and they need great teamwork skills if they want to succeed.
