Getting Started With TypeScript
TypeScript compiles into JavaScript. JavaScript is what you are actually going to execute (either in the browser or on the server). So you are going to need the following:
- TypeScript compiler (OSS available in source and on NPM)
- A TypeScript editor (you can use notepad if you want but I use vscode 🌹 with an extension I wrote. Also lots of other IDES support it as well)
TypeScript Version
Instead of using the stable TypeScript compiler we will be presenting a lot of new stuff in this book that may not be associated with a version number yet. I generally recommend people to use the nightly version because the compiler test suite only catches more bugs over time.
You can install it on the command line as
npm install -g typescript@nexthttps://basarat.gitbooks.io/typescript/content/docs/getting-started.html
