Advanced Linting in Node js
summary
Argues that linting must go beyond style to detect real bugs by enforcing patterns, demonstrates writing custom ESLint rules with ESLint and ASTExplorer.net, builds a ~20-line rule that flags a promise used inside a callback and shows it removing errors, points out existing rules like no-throw-literal and mentions publishing as eslint-plugin-promise which thousands use, and claims this approach catches mismatched callback/promise, lodash/underscore, and other pattern bugs early.
