# Jay's Typescript Setup Notes

## In Terminal

Add typescript globally to to my computer
```
npm install -g typescript
```

Check to make sure it worked
```
tsc --version
tsc --help
```

## Setup a simple example

First create a simple config file to build from the typescript files
- see attached tsconfig.json

Create helloworld file in typescript
- see attached helloworld.ts

Build in VSCode with tsconfig.json
- see that it produced a helloworld.js file
- see that it produced a helloworld.js.map file

## Run in terminal to make sure it spits out 'Hello World'
type this in
```
node helloworld.js
```

### Voila!
