For instance we can create a variable in JavaScript by just coming up with any name we want for it. You could store a string and you could store other types of data as well. You could store different things in there. So think of variables as little boxes that hold information.
Two main types of variables that you use are numbers and strings. When you have text in quotes like this it's called a string. Now when I run it you'll see that the fourth line there outputs that text. So I can do console.log and then in quotes I can put some text. You can use regular characters when outputting things. So note you can do more than just numbers. When doing multiple lines in JavaScript the convention is to use a semi-colon after each line. When I run that you can see all three results. So we can have multiple lines here like this. Now when we run it we'll see the output from every console.log. Click on this button to switch to a more complex output area here and go to Messages. What we want to do now is switch at the bottom here. Instead we can use the command console.log and put the equation in parentheses. So if you're writing a more complex program that is going to output several different things this isn't going to work. While it's nice to see the output from a program at the bottom of the screen instantly, this result area will only give you one output. You use the asterisk to multiply and then as we saw before a slash that will divide. The dash or the minus symbol will subtract them.

For instance the plus symbol will add numbers together. In JavaScript and other computer languages you can use different symbols from mathematical equations.
Instead of hitting this Run button I'm going to use Command R, the shortcut, and you can see there is the result at the bottom. But you can type something much more difficult like something like this which would be a little harder for a person to calculate but the computer can do it easily. Now 1+1 isn't very hard for a human to calculate so it's not too impressive when a computer can do it. If you don't see an area here at the bottom you can click this button here. So you can type 1+1 here and then use the Run button here at the top and you'll see the result in the bottom. One thing I really like about ScriptEditor is just like computers in the early '80s you can type a command and immediately see the results. So skills you learn in JavaScript you can then apply to any language you want to learn after that. But more importantly it looks very similar to most other modern computer languages. JavaScript is a modern programming language that's used on just about every webpage you have ever been to. By default the window will be set to AppleScript. In ScriptEditor you can work in two different programming languages. Then go to File, New to create a new document.
So to launch ScriptEditor use Spotlight, Command Space and then type ScriptEditor and hit Return.

Here's a short mini-course, divided into six quick lessons, that can get you started with programming even if you've never written a line of code before. You can use ScriptEditor to get started with computer programming just like you could with those early personal computers. However, Mac's come with an app called ScriptEditor.

Computers today come with a lot of great functionality but it's hard for somebody to get started learning how to program. Computers, like the Apple II, greeted with a blinking cursor when you turned them on and you could start playing around with code. So when I started with computers in the early '80s it was easy to learn programming. There you can read more about the Patreon Campaign. MacMost is supported by more than 500 viewers just like you.
