ESLint

[3] After contributing to JSHint, Zakas decided to create a new linting tool in June 2013, ESLint (originally called JSCheck, but renamed a month later), where all rules are configurable, and additional rules can be defined or loaded at run-time.

[13][14] JetBrains provides integrated support for ESLint in their WebStorm code editor, which runs the ESLint software as configured for the current text file, and displays any warnings near the offending lines of code in the editor.

[15][16][17] Since 2016, the Vue.js project provides an ESLint plugin to automatically validate use of Vue.js templates and other features.

[21] In October 2018, the React project (developed by Facebook) published an official ESLint plugin to help enforce their coding rules.

[22][23] As of 2021, ESLint is the most commonly used JavaScript linter and is being downloaded over 14,000,000 times per week.
