Certified Software Developer Frontend JavaScript

Course overview

This course combines classic frontend development with AI-supported programming. JavaScript is a complex programming language that allows for the creation of dynamic websites that can be tailored to users. The versatile scripting language enables development on the frontend, backend, as well as mobile apps and browser extensions. You will learn to program interactive web applications - for example, for online shops or company presences - in the browser. AI accompanies you in two roles: as a tool in everyday development and as a component of the applications themselves. You will integrate AI language models through your own interfaces, develop AI-supported functions such as chat and text processing, and learn to safely review generated code.
