This is the second course in the four‑course Computational Thinking with JavaScript Specialization. Building on the foundations from Course 1, the emphasis here is on modelling aspects of the real world using computational representations, particularly data.

You will deepen your understanding of computational thinking by working with abstract data structures and simple analytical processes. Using JavaScript and specialised libraries, you will write programs that process, analyse, and visualise data, supporting reasoning about patterns and behaviour. Throughout the course, attention is given to how data is represented, transformed, and interpreted, and to how these choices shape what a computational model can reveal. This course is suitable for learners who have completed Computational Thinking with JavaScript 1: Draw & Animate, or who already have basic JavaScript experience and want to explore data and analysis in a structured and supportive setting. The skills developed here form an essential bridge between expressive programming and the interactive, web‑based systems explored in later courses.
