Comparing the very basics of Ruby, Python, and Javascript syntax with a simple example

ruby-python-js-comparison.md

Goal

Iterate over an array of numbers and print each value

Python

array = [1,2,3,4]

for number in array:
	print(number)

Ruby

array = [1,2,3,4]

array.each do |number|
	puts number
end

Javascript

var array = [1,2,3,4];

array.forEach(function(number) {
	console.log(number)
});

It's a little confusing that you did the same thing twice in the Python one.

@Mr0grog: realized I left the 2nd one in :P

@calvinmetcalf: updated! I'm mostly a plumber in JS, so that's why it's great to have other people take a look.
