Setup Mac OS X

I've done the same process every couple years since 2013 (Mountain Lion, Mavericks, High Sierra, Catalina) and I updated the Gist each time I've done it.

I kinda regret for not using something like Boxen (or anything similar) to automate the process, but TBH I only actually needed to these steps once every couple years...

What are we trying to observe? Raw object data.

// Objects
var obj = { id: 2 };
obj.id = 3; // obj == { id: 3 }
 
// Arrays
var arr = ['foo', 'bar'];
arr.splice(1, 1, 'baz'); // arr == ['foo', 'baz'];
