1. Olivia Zhang - Writing code to refactor code - a practical guide to Abstract Syntax Trees

This talk is intended for JavaScript developers with all levels of experience, people attending the talk will learn
- What is the Abstract Syntax Tree
- How to use the AST to write Babel plugins
- How to use Babel plugins as codemods and as build-time transforms
The key takeaway is that working with the AST is easy, useful and fun!

The talk will give attention to building features in GraphQL that I found unclear at first or not well documented. I'll demonstrate:
