The popular programming language TypeScript has been widely adopted by developers in recent years. It is a superset of JavaScript that enhances the language with static typing and other features to make complicated application development simpler and error-prone. However, TypeScript code must be compiled into JavaScript because it cannot be performed directly in a browser or server. Any developer using TypeScript must comprehend how TypeScript compilation operates. There are multiple processes in the TypeScript compilation process, including parsing, type-checking, outputting JavaScript, bundling, and execution. The TypeScript compiler parses the code during the parsing phase and creates an abstract syntax tree ... Read More
