Closures

Domknięcie występuje wtedy gdy funkcja może zapamiętać oraz uzyskać dostęp do swojego zakresu leksykalnego nawet po jej wykonaniu na zewnątrz tego zakresu:

function  hello(name)  {
	//ta zmienna nie zostanie zapamiętana ponieważ
	// nie jest używana przez zwracaną funkcję
	let zmienna = "zmienna";

Install Git for Windows
Install Node
Install Python 2.7.3
Install Microsoft Visual Studio 2015 Community
Open the command prompt as Administrator, run the following commands, then close the command prompt (a new prompt is required before the new environment variables will be available)
- npm install -g npm
  - (Upgrades to npm v3, which no longer nests dependencies indefinitely. No more "maximum path length exceeded" errors due to the 260 character path limit in Windows, or needing to delete node_modules with rimraf.)
- setx PYTHON C:\Python27\python.exe /m
  - (May need to change path to your custom install directory.)
Open a new command prompt and run the following commands. If these install without errors, you have bypasse
