About the Course

Do you realize that the only functionality of a web application that the user directly interacts with is through the web page? Implement it poorly and, to the user, the server-side becomes irrelevant! Today’s user expects a lot out of the web page: it has to load fast, expose the desired service, and be comfortable to view on all devices: from a desktop computers to tablets and mobile phones. The course covers fundamental Javascript programming concepts, starting with variables, data types, operators, and control flow mechanisms. It will then teach learners about object-oriented programming in Javascript, object creation using literals and constructors, prototypes, and the intricacies of the 'this' keyword. After which, the course goes into the power of Javascript arrays, using namespaces and IIFEs to prevent variable collisions, and discussion of closures and their use cases in Javascript programming. After covering the fundamental Javascript programming concepts, the course transitions into building dynamic and interactive websites by using Javascript and AJAX (Asynchronous JavaScript and XML) to interact with the Document Object Model (DOM), handle user events, and dynamically update web page content. The course will also talk about the HTTP protocol, different HTTP request methods, and how to work with JSON data. Building on these skills, learners will gain practical, hands-on experience by converting the restaurant website into a dynamic single-page application (SPA) powered by Javascript and AJAX....

The real-workd projects were invaluable for translating concepts into real-world applications

Great course! If I had studied more "basic JS syntax" before I started, I would have enjoyed it more.

It is good overall but the versions used are so outdated, I hope they put a year on when was this course published. Thanks Yaakov!

The first module of this course is great, the second module of this course not so much, on the last section of the second module, there is a gap of information/steps that isn't provided in order for us to follow along on our own (setting up and using firebase, for example). I like to follow along and write the code on my end so to see these steps get completely skipped was really disappointing

Because this is an "Introduction" I wouldn't expect the phrase "you should already have some programming experience" to be used during the course. I "learned" of course, but man it was a struggle. It may be just my learning style, but I feel like the Ajax portion was rushed so it was hard to follow at times.

Course is pretty outdated. The start is good, but it falls off later. There is too much videos compared to assignments
