In many other languages, you need to download the software that is compatible with the language in your machine to access all the features of the language and create a development environment. Whereas with JavaScript any individual with a web browser suddenly has a development environment right in front of them. Every browser supports JavaScript!
One of the most impressive features of JavaScript is that it includes event-based programming. It has multiple built-in events like ‘onHover’ and ‘onClick’ that wait for user interaction on a site before executing a specific segment of the code. For example, when you click the night-mode toggle, an event that triggers a JavaScript code segment that changes the CSS present across the whole website from lighter colors to darker colors.
The popularity of JavaScript led to the creation of several libraries and frameworks that have made application development efficient and performant. Today, libraries like React JS, D3.js, jQuery, etc. are used in most applications across the world. Frameworks such as Vue JS, Angular JS, and Ember JS provide optimal performance and organization to build large applications.
Node.JS is a runtime environment that runs JavaScript code outside of a web browser and lets the developers use JavaScript to write server-side scripting. As a result, JavaScript’s popularity was dramatically increased because Node.JS represented the idea of the “JavaScript everywhere” archetype, amalgamating all of web application development around a single programming language, rather than having a different language for client-side and server-side scripts.
JavaScript online test is designed and validated by industry experts to help tech recruiters and hiring managers to assess JavaScript programming skills of the candidate. Top tech companies are using our JavaScript programming test to reduce candidate screening time by 85%.
The JavaScript test screens candidates for the following skills:
The insights generated from this assessment can be used by recruiters and hiring managers to identify the best candidates for the role. Anti-cheating features enable you to be comfortable with conducting assessments online. The Javascript developer test is ideal for helping recruiters identify which candidates have the technical skills to do well on the job.
JavaScript (JS) is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB, and Adobe Acrobat. About 1/3rd of all developer jobs require some JavaScript knowledge.
JavaScript developers can target more platforms than any other high-level language, as JavaScript is the most popular programming language with the richest OSS module ecosystem available. It is used to create interactive web pages, user experience, and responsive front-end design. Anything a user clicks, inputs, edits, or pulls up on a website is possible. This JavaScript Online test is designed to help you find the best JavaScript engineers for your role.
The actual score distributon will vary based on your candidate pipeline quality, but you should typically expect ~20% of the candidates to do well on Adaface assessments.
The score distribution for our assessments follow the normal curve. This is a good sign- standardized tests like SAT and GRE follow the normal distribution (bell curve).
Status quo assessments typically have the exact opposite of the bell curve (too many candidates getting close to 0, too many candidates getting close to 100 and too few candidates in the middle). This is typically because they focus on theoretical questions or trick questions, which are very binary in nature- either you know the trick/ theory or you don’t.

JavaScript is a scripting or programming language that allows you to implement complex features on web pages. Every time you see a web page doing more than just sitting there and displaying static information for you to look at, displaying timely content updates, animated 2D/3D graphics, interactive maps, scrolling video jukeboxes, etc., you can be sure that JavaScript is probably involved.
The test is designed to enable recruiters and hiring managers to quickly identify which candidates should be invited to an interview.
This test will assess candidates on their fundamentals and depth of JavaScript development with questions on:
The questions are designed to test for on-the-job JavaScript skills as opposed to just theoretical concepts. The programming and debugging challenges test the problem-solving and coding ability of your candidates.
Depending on the role and industry, a JavaScript developer might require these skills:
Every role is different and requires a custom assessment to identify top candidates efficiently. Adaface subject matter experts understand your job description/ role requirements and pick the most relevant questions from our library of 10000+ questions to create a technical assessment that helps you find the qualified candidates in your candidate pipeline quickly. All custom assessments are set up based on the job description, role requirements, must-have skills, experience level and salary range within a maximum of 48 hours and you will get an email notification once it goes live.
Check out a sample assessment here (no credit card required).
Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify.
We believe that status quo tech assessment platforms are not a fair way for companies to evaluate engineers because they focus on trick questions/ puzzles/ niche algorithms. We started Adaface to help companies find great engineers by assessing on-the-job skills required for a role. Read more about why we started Adaface.
Here's what's different with Adaface:
We have the following anti-cheating features in place:
Read more the proctoring features.
The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. As in an assessment is optimizing to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 60%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.
Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.
Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.
No. Unfortunately, we do not support practice tests at the moment. However, you can use our sample questions for practice.

The platform is completely self-serve, so here's one way to proceed:
Here is a quick guide on how to request a custom assessment on Adaface.
The screening signals that technical recruiters typically use: fluffed-up resumes, Github profiles, StackOverflow activity, educational qualifications and previous employers are noisy.
What it is, types and benefits, reservations against them, the rise of candidate friendly assessments and AI tools, and the best practices for implementing pre-employment testing in your company.
Most engineers today frown at the idea of completing a coding test, and over 50% straight out refuse to do status quo assessments (based on our research with 100+ companies in SEA).
With Adaface, we were able to optimise our initial screening process by upwards of 75%, freeing up precious time for both hiring managers and our talent acquisition team alike!
