Install k6 type definitions

k6 has its TypeScript Type Definition that you can configure with your editor to unlock code editing features.

In Visual Studio Code and IntelliJ IDEA Ultimate, you can configure IntelliSense to recognize the k6 JavaScript API by installing the k6 Types with a package manager.

Bash 
# create a `package.json` file
$ npm init --yes

# install the k6 types as dev dependency
$ npm install --save-dev @types/k6
