What is a JavaScript test?

A JavaScript test assesses a candidate’s overall JavaScript coding skills. The test requires applicants to interpret code and solve common issues and is ideal for testing the competency of entry-level developers.

A candidate’s performance on the test can be compared to other applicants to distinguish those who are qualified for the role and those who don’t quite fit the bill. A high score indicates a candidate holds a strong understanding of the JavaScript language and has the potential to apply those skills on the job.

A JavaScript test can be coupled with other coding and skills tests, to give a fuller picture of a prospective employee’s technical strengths. It can also be combined with personality or aptitude tests to provide a holistic view of each candidate.

About the JavaScript Test

Proficiency in JavaScript is essential for most developers, as it enables interactive web pages and forms the basis of web applications. Nearly all web pages contain JavaScript, as it is used in both front-end and back-end web development and is central to the creation of mobile apps and games.

It is the foundation for web frameworks such as Angular, Vue, Ember and React. These frameworks are very popular.

Due to its core use for a variety of functions across the web, evaluating a junior developer’s JavaScript skills is a useful early step in the recruitment process.

Sample JavaScript Test question Test your knowledge!

var values = [10,20,30,40,100]; 
var result = values.reduce(function(prev, cur, index, array){  
    return prev + cur; 

Which of the following would be the value of the result when the below statements are executed?

  • 50
  • 90
  • 100
  • 200

Why should you use a JavaScript test for recruiting?

A strong knowledge of the foundations of coding, such as JavaScript, is invaluable for entry-level developers. An applicant’s resume gives an insight into their programming experience – and may list key skills – but only a practical test can confirm the level of those skills.

Developers who can display competency in basic coding skills are likely to take to their new roles faster, absorbing new skills and adapting to the needs of the workplace.

Online skills testing, tailored to the strengths required for a job vacancy, is an excellent way of streamlining the recruitment process, making objective hiring decisions, and avoiding unintended bias.

How our test assesses JavaScript skills

In Neuroworx’s JavaScript test, candidates will need to answer a range of questions targeting an intermediate level of proficiency, from demonstrating their understanding of the JavaScript language and architecture to their skills in using it in front-end and back-end development.

The test is designed to indicate how well a candidate understands JavaScript based on a final test score, which can then be compared to the scores of other applicants.

The multiple-choice questions consist of one correct answer and two-to-four distractors. The distractors are mostly generic mistakes or misconceptions, which makes the test challenging and helps measure a candidate’s proficiency more accurately.

During the development process, the test was rigorously analysed to maximise reliability and validity in line with industry best practices. It was created and reviewed by programmers and psychometric experts, and field-tested with a representative sample of job applicants who have varying JavaScript experience, just like you might find in a talent pool.

Each test is reviewed by a panel of individuals representing diverse backgrounds to check for any sensitivity, fairness, face validity and accessibility issues. This ensures each programmer has a fair chance of demonstrating their true level of JavaScript proficiency and feels the test is of high quality.

Our programming tests are monitored to ensure they are up-to-date and optimised for performance.
