Goals

Here are my goals that I would like to accomplish over the next year.

Goal #1 - Become proficient in JavaScript and its ecosystem

• Currently, I have a decent grasp over the language. There are still some ES5 methods I am not familiar with and ES6 is hit or miss with what I know. The JS ecosystem is still something I'm getting used to (npm) and using a tool like webpack is still tough to wrap my head about.
• Success would be fully understanding all the little quirks of JS and keeping up with the latest version of the language. Being able to structure modern client side applications using webpack and taking advantage of npm. Also, I would like to become fairly proficient with building out API's with Node.
• Resources for learning:
  • Nodecasts
• YDKJS

Begin!

Senior programmers won't have a problem with these, while junior programmers will usually give only half-answers.

What is a class?

A text-book answer: classes are a blue-print for constructing computer models for real or virtual objects... boring.

In reality: classes hold data, have methods that interact with that data, and are used to instantiate objects.
