Programming languages

What is a program?
A program is a special kind of file that the computer, or operating system, knows how to run.
Because computers only know about 1's and 0's, we need a way to translate something that we can understand into the computer's "language".
A programming language gets translated, or compiled, into binary.
saveFile('MyFile.jpg') -> 0001110101010011010
Just like there are a lot of spoken languages, there are many programming languages.
Example - JavaScript
Used primarily for programming websites.
Makes the website do things, like this presentation.
function say(message) {
alert('Hello' + message + '!');
}
say('World');
// Result: 'Hello World!'
