ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code. In many ways, it is similar to JSLint and JSHint with a few exceptions: ESLint uses Espree for JavaScript parsing. ESLint uses an AST to evaluate patterns in code. ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime. Table of Contents
