How do I React Component?

A variation with an unnecessary const

...since nothing in that file should be accessing that 'MyComponent' except the export.

Also that react import is very confusing though. Why do I need it? I don't reference that variable anywhere... oh wait some tool compiles the JSX for me at some point into React.createElement or whatever. Very opaque:

ES6 Shit

I started converting simple things into the cool new Babel/ES6/ES2015. Turns out that a lot of the new features are very much half-assed.

Root exports handling

Let's use export syntax to replicate:

module.exports = function () {};

Easy way to calculate SF salary requirements if you're moving from Pittsburgh.

1. Let's say you are currently paying 800/month for a nice one-bedroom in Pittsburgh.

• If you would like to stay in a one-bedroom, You will/should be paying about $2500-3500 / month for it in SF
• If you want to split with roommates, you will/should be paying $1000-2000 in SF

2. Calculate the difference between your current rent and your guestimated SF rent:

• 3200 (nice one-bedroom rent price) - 800 = 2400

3. Adjust negative car and utility
