JavaScript Coding Specialist (JCS) Certification

The JavaScript Coding Specialist Exam is a globally-recognized certification which grants coding specialists, web developers and designers the ability to validate their front-end and back-end web development skills.

JavaScript is one of the most flexible and powerful programming languages implemented across the web allowing web designers and developers to build fluid interactive web pages. It is a popular language to learn because JavaScript is literally everywhere, unifying all web application development into one programming language.

What are the benefits of getting a JavaScript Certification?

The unique peculiarity of the JCS Certification is the assessment modality, which consists of a real live coding environment, offers candidates the ability to write proper code to perform task-based questions. This technology is called LITA (Live in the Application) and Knowledge Pillars is one of the very few organizations able to provide this very advanced assessment solution.

JavaScript was initially designed to make web pages come to life. The programs in this language are called scripts. It is one of the three main languages used and the most essential part of web application today. This 25-year-old programming language is listed as the first language to be learned by people who want to program because of its full-stack capabilities, it can be used as both a frontend and backend programming language.

I am a business leader and I have a company in finance. We need very often to hire developers with Python or Javascript skills as development is an active part of our business; we need to improve continuously the stability and quality of our system, so we need people with experience. We receive between 500 and 1500 applications when we create a job post. One of the very first things we do is shortlist applications, by looking for specific words or certifications that can prove candidates have what we need.

Unfortunately, 2 out 3 candidates, even if certified, don’t seem to own quality skills and their knowledge seem to be more theoretical. KP certifications solve that issue, because now we know, in advance, that a candidate possessing those credentials must also own the knowledge in a practical way. KP significantly contribute to addressing and providing a solution to the skills gap in the modern world.
