Intermediate JavaScript Online Training

Yes, it's definitely worth it to learn JavaScript, and online courses are the best way to learn it. Taking an online JavaScript course doesn't just reveal the ways it can improve your job (and job prospects!), though. With online courses, you're not just reading information or watching videos – you have a place to practice what you're learning about and do hands-on programming practice with instant feedback about your code.

Unlike industry certifications from Microsoft, Cisco or AWS, there are no official certifications for JavaScript, since there isn't one single entity responsible for maintaining its standards. W3 Schools and the JavaScript Institute both offer certifications that represent different levels of competency with JavaScript, and they both cost a little less than $100. Time and money spent developing your skills proves commitment to excellence to current and future employers.

It's generally agreed that the basic syntax of JavaScript, how functions are defined, and the basics of arrays and objects are pretty easy to learn. At the intermediate level, JavaScript can become more challenging. Some students at the intermediate level struggle with asynchronous programming, the event loop and concurrency, and managing performance optimization. With a good course and a dedicated student, however, intermediate JavaScript is also where it gets really fun and interesting.

Technologies come and go very rapidly, and there's always an expiration date for the knowledge you gain about programming languages and protocols. And yet, JavaScript might be the exception. It's hard to overstate how crucial and fundamental HTML, CSS and JavaScript are to the entire Internet. Intermediate JavaScript skills and knowledge will almost certainly serve you for your entire career. And if somehow JavaScript goes away, whatever replaces it will be much easier to learn and understand if you know JavaScript.

When you're just getting started with JavaScript, there's a lot you can learn by setting up a small web server of your own and fiddling. But when you're moving on to more advanced JavaScript skills, it's helpful to have custom-made practice scenarios. Online courses like this one that offer practice environments and virtual simulations mean you can tackle challenging problems head-on and try different approaches – all without rebuilding the starting conditions on your own.
