TypeScript is a popular programming language that extends JavaScript with new features and syntax. In order to use TypeScript, you’ll need to install it and run the TypeScript compiler, tsc.
Installing TypeScript is simple and can be done in several ways, including using npm (Node Package Manager) or by installing it globally on your computer. If you’re using npm, you can install TypeScript by running the following command in your terminal:
npm install -g typescriptOnce you’ve installed TypeScript, you can use the TypeScript compiler, tsc, to compile your TypeScript code into JavaScript. The tsc command takes your TypeScript code and converts it into JavaScript, which can then be run in any browser or JavaScript environment.
The tsc command can be run from the command line, and it requires you to specify the TypeScript file or files that you want to compile. For example, if you have a TypeScript file called index.ts, you can compile it by running the following command in your terminal:
tsc index.tsWhen you run this command, the TypeScript compiler will generate a corresponding JavaScript file, index.js, that contains the compiled code. You can then run the JavaScript file in any JavaScript environment, such as a browser or Node.js.
It’s important to note that the TypeScript compiler has a number of options and configurations that you can use to customize the way it compiles your code. For example, you can set the target version of JavaScript that your code should be compiled to, or you can specify that the compiler should perform strict type checking.
In conclusion, installing TypeScript and running the TypeScript compiler, tsc, is a simple and straightforward process. By using TypeScript and the tsc compiler, you’ll be able to write more robust and scalable code that takes advantage of the advanced features and syntax of TypeScript.
