Introducing linters – Prettier, ESLint, and StandardJS

In a nutshell, a linter is a tool that analyzes source code and flags errors and bugs in the code and styles. The term originated in 1978 from a Unix utility called lint that evaluated source code written in C, and was developed by computer scientist Stephen C. Johnson at Bell Labs while debugging the Yacc grammar he was writing. Today, the tools we focus on in this book are Prettier, ESLint, and StandardJS. Let's look into each of them.
