Intermediate JavaScript and jQuery Course

About This Course

JavaScript is used to make web pages interactive. Things like forms, animations, and anything to do with data is handled by JavaScript embedded in a webpage. This includes things like creating accounts and signing in, saving preferences, or posting messages. JavaScript has been around for 20 years, but only within the last 5 years have its capabilities and adoption exploded. Today, it is one of the fastest growing areas within the programming landscape.

jQuery is a JavaScript library that simplifies many common tasks done in vanilla JavaScript. jQuery is really good at handling “events” on a webpage like when someone clicks or moves their mouse. jQuery is also good at finding(selecting) a small part of a webpage and making very specific changes to that part.

The Intermediate JavaScript and jQuery training course will allow your team to take a deeper dive in to the web’s most popular programming language while also learning more about its most popular library.

I had trouble understanding a certain concept, and told the instructor that I just didn't get it. While the class was busy with an exercise, he sat down with me, gave me material to read, and made sure I understood it before I moved on. I really appreciated that.
