JavaScript programming

During this training, we will cover the main programming possibilities for client-side JavaScript, based on the ECMAscript standard. After an introduction to the syntax we will create dynamic web pages using the Document Object Model (DOM). We will discuss the usage of events to handle form submission and validation.

Next to the "classical" JavaScript, we will also cover topics needed to create larger, structured JavaScript applications. This will include using classes, modules. and an introduction in Single-Page Applications (SPA) and API calls.

At the end of the course, we will discuss other JavaScript technologies, such as Typescript, Node.js and Bootstrap, and provide an overview of the current JavaScript libraries and frameworks.

After attending this course, participants will be capable of enhancing a website with JavaScript. They will have acquired a good strong working knowledge of the fundamental concepts of JavaScript in relation to HTML and will be prepared to work on larger applications (potentially using web component libraries like LIT or frameworks like Angular).
