tsc is the TypeScript compiler, which is a crucial tool for developers working with TypeScript. It takes TypeScript code and compiles it into JavaScript, ensuring that the code adheres to TypeScript's strict typing system. The tsc command is typically used in the development process to check for type errors and to produce JavaScript output that can be executed in various environments. While tsc is a powerful tool for TypeScript projects, there are several alternatives and complementary tools that developers can consider:

• babel is a widely-used JavaScript compiler that allows developers to use the latest JavaScript features without worrying about browser compatibility. While Babel primarily focuses on transforming JavaScript code, it can also be configured to work with TypeScript by using the appropriate presets. This makes Babel a good choice for projects that require both modern JavaScript features and TypeScript support, especially when integrating with existing JavaScript codebases.
• esbuild is an extremely fast JavaScript bundler and minifier that also supports TypeScript. Its speed comes from being built in Go, which allows it to compile and bundle code much faster than traditional tools. If performance is a critical factor in your development workflow, esbuild is an excellent choice for compiling TypeScript code quickly and efficiently.
• swc is a super-fast JavaScript and TypeScript compiler written in Rust. Similar to esbuild, swc aims to provide a high-performance alternative to Babel and TypeScript's tsc. It supports modern JavaScript features and TypeScript, making it a suitable option for developers looking for speed and efficiency in their build processes.
• ts-loader is a TypeScript loader for Webpack, allowing developers to use TypeScript in their Webpack build processes. It integrates seamlessly with Webpack, enabling developers to leverage the benefits of both tools. If you are already using Webpack for bundling your application and want to incorporate TypeScript, ts-loader is the ideal solution.
• typescript itself is the language and its associated tooling, which includes the tsc compiler. It provides a robust type system and modern JavaScript features, making it a popular choice for building large-scale applications. Using TypeScript directly allows developers to take full advantage of its features, including type checking and advanced tooling support.
