Master the Art of the AST

A presentation at Codemotion Tel Aviv in in Tel Aviv-Yafo, Israel by Yonatan Mevorach

Think about the new tools that are taking over the Javascript ecosystem: Babel, Typescript, Rollup, ESLint, and smarter IDEs. This talk will be a deep dive into the basic building block all these tools share: Transforming your code into a JS Abstract Syntax Tree (AST). You'll learn to read, traverse, and manipulate the AST so you can extend Babel by writing your own plugins, or by writing a custom ESLint rules to enforce your team's code conventions. You'll also learn how to create super powerful "code-mods" to automatically convert thousands of legacy ES5 scripts to ES6 in seconds.
