In this class, I learned what is front-end? We learned and used a series of front-end technologies such as HTML, CSS, etc., and we were able to implement animation effects. The HTML course allowed us to learn the document structure and basic syntax of it, to understand the features of HTML, the basic syntax of CSS and the layout! (Wing 2006) studied that whether computing operations are carried out by a human or a machine, computational thinking builds on the strengths and weaknesses of such operations. We have the confidence to solve issues and develop systems that none of us could do on our own thanks to computational methods and models. Therefore, using the fundamental ideas of computer science, computational thinking is a set of thought exercises that span the range of computer science, including problem solving, system design, and understanding human behaviour. This broad idea makes it clear that, despite being based on computer science, computational thinking is not just applicable to computer conversion. Rather, it can be said that computational thinking is a concept that is applied to other fields of thought, and when problems arise, they are resolved using this method of problem-solving.
