# Scaling Best Practices with Syntax Trees
> Slides and material for a conference talk
## Proposal
There's a myriad of good and bad ways to write our JavaScript-and it keeps evolving! ES2015 is here, ES2016 is coming soon, and the language is changing faster than ever.
Fortunately, there is also a revolution in JavaScript tooling. New tools are here to help us understand and improve our code. Let's look at one of these tools, ESLint, and write our own rules to detect patterns in computer language. While we're at it, let's rediscover how languages are parsed, analyzed, and represented as abstract syntax trees.
## Slides
[Midwest.io - November 2015](http://slides.com/willklein/scaling-best-practices)
[Nodevember - November 2015](http://slides.com/willklein/scaling-best-practices)
## Code
The slides have a simple, self-contained example, along with the code snippet for a simple ESLint rule. This repo has a richer example, a clone of TodoMVC in React. It also has the same rule broken out into a plugin, along with tests that you can run to experiment with modifications.
### Testing
To run the Mocha tests for the ESLint plugin, `cd` into the `code/eslint-plugin-demo` directory and run:
npm test
