How Linters, Compilers & Other Cool Things Work

Explore the inner workings of JavaScript tools and the abstract syntax tree (AST) in this 22-minute conference talk from CascadiaJS 2018. Gain insights into how compilers, linters, and other development tools function, learn how to extend them, and deepen your understanding of computer language. Discover the power of ASTs in automated code reviews, Babel transformations, and API changes. Dive into topics such as declarations, variable properties, conditional expressions, and object properties to enhance your knowledge of JavaScript's underlying structures.
