Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

You Don't Need CoffeeScript

It's time to replace CoffeeScript with Babel and CoffeeLint with eslint.

CoffeeScript was useful a few years ago. It provided many features that JavaScript was lacking. It gave us the fat arrow (lexical this functions), default parameters, destructuring assignments, splats (spread operator), a class keyword, block strings, and more. Everything in the list above is now part of the JavaScript standard. JavaScript is moving forward and gaining

Thinking Like a Function

Part 1: What's a function?

As a software engineer, you probably think of a function as a unit of code that takes some arguments and returns some value, eg:

 function square(x) { 
   return x * x;
 }

System Component Inputs & Outputs

Evaporator

Composed of evaporator coils & refrigerant line.

Refrigerant passing through coils absorbs thermal energy from unconditioned air, resulting in cooler & drier air. This air is discharged into the living space.

• Input: Low-pressure, low-temp liquid/vapor-mix coolant.
  • From: TXV
• Output: Low-pressure, low-temperator coolant vapor.
