Now that we have learned how to use npm, we can install TypeScript using the following command:

    npm install typescript -g

The TypeScript compiler will then become available in our CLI as a command named tsc. We can check the version of TypeScript installed in our machine using the following command:

    tsc -v  

The TypeScript compiler accepts many more options. For example, we can use the --target or -t option to select which version of JavaScript we would like to target as the compilation output:

    tsc --target es6  

Alternatively, we can create a tsconfig.json file to set the desired compilation settings. We can also use the TypeScript compiler to autogenerate a tsconfig.json file with default settings using the following command:

    tsc --init  

After creating a tsconfig.json file, you can pass it to the TypeScript compiler using the --project...
