Creating web applications using the transpiler TypeScript 4.2

The goal of the bachelor thesis will be a comprehensive elaboration of the new version of the TypeScript 4.2 transpiler, which is intended to facilitate the work with the JavaScript language on which it is based. TypeScript is an open-source programming language, created and maintained by Microsoft, it is actually asuperstructure over JavaScript, which extends it with static typing and other attributes we know from object-oriented programming. The code itself, written in TypeScript, is then compiled into JavaScript, with the compiler having the ability to auto-complete and correct errors before running JavaScript code. The theoretical part of the thesis will focus on TypeScript itself, comparing it with JavaScript itself, evaluating the advantages, disadvantages and differences, introducing the syntax and current features using the React JS framework, which is used by many developers to create web applications. The practical part will then consist of a~series of demonstrative web applications, written in TypeScript, which will be hosted on their own website and documented
