This course is a hands-on introduction to programming of mobile applications. Building on basic JavaScript programming skills, React Native is introduced as the preferred framework for cross-platform mobile application development. The concept of Location-Based-Services is also introduced in combination with React Native and is explored hands-on, in combination with programming hardware components on the phone (e.g. camera component). Student work revolves around small weekly individual tasks and readings of React Native documentation (online resources and provided course material) and a group project (3-4 students) that will be carried out in the second half of the course.
