And now an intro to Git!

It's completely possible to use git without knowing these things (especially with some of the guis), but a glimpse into the internals will actually make it a lot easier to use and remember why things are the way they are, even if it looks confusing at first. It's actually not that bad!

In TFS there is one server. When you check out the code, you copy the latest version of each file's contents down to your working directory. The change log is linear, meaning you can view history and see commits 1 through 48561 all in a row. When you want to check in changes you need to contact that server. If you want to see an old version of the file you have to contact that server. If you want a "branch" you have to copy all the code to a new folder and maintain the changes between the two. A TFS server is a web service where all "intelligent" operations are carried out by that single server. If you can't get online or the server is down, you're out of luck.

If your language works like this by default..

var x = {a: 5};
var y = {a: 5};
x === y; // => false

Nodejs!

What's node?

Node is a program (usually run from the command line) which executes JavaScript, and comes with a built-in library for writing network and filesystem code. Node is built on V8, the same JavaScript VM used in the Chrome browser. Instead of being wrapped with a GUI and web browser features like the DOM, node wraps V8 to expose lower-level operating system APIs. Some modules that come with node include: http, fs (filesystem), crypto (cryptography), and lots more.

What's a module?

Modules are chunks of code you can 'require' and then use. Today we'll use the http module, like so:

var http = require('http')

PureScript

What is it?

• Compiles to JavaScript
• Haskell-inspired type system (with some improvements!)
• No runtime (unlike Elm, GHCJS, etc)
• A focus on readable and debuggable JavaScript
