Single thread for single program

Link to original

A single thread runs the entire program. No two tasks can run at the exact same time.

Blocking

Code that blocks like nodeJS syncing functions will end up stalling and preventing the other code to run, while it performs its operations. Blocking code should always be turned into NodeJS Events, to make them Asynchronous. Example:

readFile('hello.txt', 'utf8', (err, txt) -> {
	console.log(txt)
})
