What is @babel/preset-typescript?
The @babel/preset-typescript package is a Babel preset for TypeScript, which allows Babel to parse and transform TypeScript code into JavaScript. This enables developers to use TypeScript's static typing features while leveraging Babel's ability to compile modern JavaScript to be compatible with older browsers or environments.
What are @babel/preset-typescript's main functionalities?
TypeScript Compilation
Compiles TypeScript code to JavaScript by stripping out type annotations and handling TypeScript-specific syntax.
const x: number = 10;
Support for TypeScript Features
Supports various TypeScript features like enums, interfaces, and namespaces, converting them to equivalent JavaScript code.
enum Color { Red, Green, Blue }; let c: Color = Color.Green;
Integration with Babel Toolchain
Easily integrates with the Babel toolchain, allowing TypeScript files to be included in Babel's build process alongside other JavaScript files.
module.exports = { presets: ['@babel/preset-typescript'] };

ts-loader
ts-loader is a TypeScript loader for webpack. It compiles TypeScript to JavaScript before bundling. It differs from @babel/preset-typescript in that it is specifically designed for use with webpack and uses the TypeScript compiler (tsc) directly rather than Babel.
awesome-typescript-loader
Similar to ts-loader, awesome-typescript-loader is another loader for webpack that compiles TypeScript to JavaScript. It offers features like Babel integration and type checking in a separate process. It is an alternative to ts-loader and provides similar functionality to @babel/preset-typescript but with a focus on webpack integration.
typescript
The official TypeScript npm package provides the TypeScript compiler (tsc) which can be used to compile TypeScript files directly without Babel. It is more comprehensive in terms of TypeScript feature support compared to @babel/preset-typescript, which is focused on integrating TypeScript with Babel's ecosystem.
