# After installing Node (https://nodejs.org/en)
npm i -g typescript

# Check tsc is installed
tsc --version

# Create an index.ts file
echo "console.log('hello world')" > index.ts

# Can't run ts files directly by themselves - have to compile as .js
tsc index.ts

# Or open another bash window and keep index.ts autocompiling (-w / watch)
tsc -w index.ts

# Can then run the .js file in the console
node index.js

# Try installing a module / 3rd party library
npm i lodash
npm i -D @types/lodash
