JavaScript Coding Specialist 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 JSCS 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.
