Nicholas C. Zakas is announcing that ESLint with version number 1.3.1 is already available to download.

What is ESLint ?

ESLint is A code linting utility for JavaScript code, a powerful toolkit for parsing and detecting problems in your JavaScript syntax without actually executing it . ESLint is a must-have tool for every JavaScript developer, especially code testers.This utility lets them analyze a JavaScript file for common syntax-related problems, getting a simple report at the end about encountered problems.ESLint checks JavaScript code against a set of customizable rules, rules which developers can activate or turn off based on their (company's) internal coding style guides.A set of built-in rules are provided with the standard package, but ESLint's main feature is its powerful Rules API which will let anyone build their own set of rules if they don't find what they're looking for in the original ESLint distribution.By default ESLint uses standard ECMAScript 5 syntax, but since version 0.12 basic ECMAScript 6 features have been slowly added to the core.ESLint was inspired and modeled after similar JavaScript linting tools like:- JSLint- JSHintCompared to the aforementioned tools, ESLint is slower because it creates AST trees for the parsed code instead of parsing and analyzing it as it goes. This slows it down, but provides better linting results.Because of these better results, projects like Drupal, Esprima, or the WebKit engine itself use it over other tools. This is changelog for ESLint version 1.3.1 :

• Fixed:
• loc obj in report fn expects column.
