About the JavaScript (Coding): Debugging test

JavaScript is a flexible and powerful programming language that has been evolving very fast with the introduction of classes, generators, arrow functions, and many other features.

The ability to understand and debug code is a critical skill for a successful JavaScript developer. As new features are being developed for an application, bugs may be introduced into the code, and it is important for a developer to be able to identify and fix them. Given the collaborative nature of software development, it is also critical for developers to be able to work with and correct the code of others.

This test gives candidates a small script that contains one or more bugs. The description clarifies the objective of the code and provides examples to illustrate how it should function. Candidates must identify and fix the bugs.

We recommend combining this coding test with other programming tests such as Angular, React, Vue.js, Node.js, and SQL, as well as our tests on critical thinking and numerical reasoning.

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.
