JavaScript programming

This course covers the main programming possibilities for client-side JavaScript, based on the ECMAscript standard. After an introduction on the syntax and coding instructions of JavaScript blocks, we delve into variables, types and handling objects, properties and methods. Usage of core JavaScript objects like String, Date, Array, ... is discussed in more detail.

The course explains as well how JavaScript accesses the browser via the Browser Object Model (BOM), and more specific the browser page or document via the Document Object Model (DOM). Manipulation of the DOM, based on the event model, for validation and data preparation, will be the first step for interaction with a backend system.

Coding, testing and debugging JavaScript features will be illustrated for different environments. Some common JavaScript frameworks and libraries will be positioned as well.

After attending this course, the participant will be capable of embellishing a website with JavaScript, e.g. to implement field validation in forms. He/she will have acquired a good working knowledge of the basic concepts of JavaScript in relation to HTML.
