Question 1

What is OpenJS and what is NodeJS application development?

Accepted Answer

OpenJS is a professional organization, it's made up of JavaScript developers and professionals who are trying to solidify and improve the future of JavaScript. Node.js is a JavaScript runtime built for Chrome's V8 JavaScript engine. Node.js has libraries, tools and a community that was, at one time, popular for building web servers and backend APIs, but has since expanded far beyond those to streaming, IoT, microservices and more.

Question 2

Is there any official certification for JavaScript or Node.js?

Accepted Answer

Yes, there are official certifications for proving familiarity and expertise with JavaScript and Node.js. JavaScript is an open standard, so there isn't a single organization that "owns" it like other proprietary technologies, but nonetheless organizations like OpenJS and The Linux Foundation are globally recognized as the authorities on JavaScript and Node.js best practices and professional certifications, providing validation of proficiency for developers while enhancing industry standards and collaboration.

Question 3

What does a Node.js application developer do?

Accepted Answer

A typical day for a Node.js application developer will vary a lot from one job to the next, but many of the core expectations remain the same. A Node.js developer designs, builds, and maintains server-side software with JavaScript. They use the Node.js runtime to build scalable web servers, APIs and other back-end applications. A Node.js app developer writes codes, implements features, debugs and generally optimizes performance.

Question 4

Are Node.js certifications worth it?

Accepted Answer

Yes, in an industry like development, certifications from the Linux Foundation like the JSNAD (OpenJS Node.js App Developer) are worth it. There aren't many credentials that are internationally recognized representations of a certain amount of skill and knowledge creating web-based applications. The Linux Foundation has an excellent reputation for developing certifications that prove a developer's readiness and proficiency in Node.js app development, enhancing job prospects and credibility.

Question 5

Was Node.js discontinued? Is Node.js still relevant?

Accepted Answer

Not only was Node.js not discontinued, it remains as relevant as it ever was – maybe more. Some people believe that Node.js was discontinued or became unsupported, but this is not true: Node.js and the JS Foundation merged and formed the OpenJS Foundation. The OpenJS Foundation remains committed to the Node.js environment, so although misconceptions exist, Node.js is actively maintained and widely used in modern web development.
