jslint

I'm totally cool with this JSLint error. How can I tolerate it? Is there a flag or checkbox for it? You get it when you do stuff like: v && arr.push(v); as opposed to: if (v) { arr.push(v); } Both do the same exact thing. If you put: window.test = function(v) { 'use strict'; var arr = []; if (v) { arr.push(v); } return arr; }; into the minifier it minifies down to this anyway: window.test=function(a){var b=[];a&&b.push(a);return b}; I don't think JSLint has an option to turn that off. JSHint (a fork with more options) has an option for it, though: The expr option, documented as "if

Javascript code can be tough to maintain. I am looking for tools that will help me ensure a reasonable quality level. So far I have found JsUNit , a very nice unit test framework for javascript. Tests can be run automatically from ant on any browser available. I have not found yet some javascript equivalent of PMD, checkstyle, Findbug... Do you know any static code analysis tool for javascript ? This is an old thread, but if you're interested in running Jasmine for BDD testing in your maven project, I wrote this jasmine-maven-plugin for exactly this purpose (that is, improving JS quality by

I've run JSLint for the first time on a rather lengthy file, and I have a lot of errors like expected exactly 1 space between "function" and "(" or unexpected ' ' . I didn't realize this was important at all anywhere I learned about javascript and now fixing each one of these rather simple things by hand seems frustrating. Some I can figure out with simple find and replaces, but I wondered if there's any tools online that will automatically make these changes for me since they seem to be pretty straightforward? (I have /*jslint white: false */ in my file, I develop in Netbeans and auto-format

JSLint is not passing this as a valid code: /* global someVar: false */ if (typeof someVar === "undefined") { var someVar = "hi!"; } What is the correct way? bigoldbrute /*global window */ if (window.someVar === undefined) { window.someVar = 123456; } if (!window.hasOwnProperty('someVar')) { window.someVar = 123456; } /** * @param {string} nameOfVariable */ function globalExists(nameOfVariable) { return nameOfVariable in window } It doesn't matter whether you created a global variable with var foo or window.foo — variables created with var in global context are written into window. If you are

This is the error I get when using const: <error line="2" column="1" severity="warning" message="&apos;const&apos; is available in ES6 (use esnext option) or Mozilla JS extensions (use moz)." source="jshint.W104" /> My code looks like this: const Suites = { Spade: 1, Heart: 2, Diamond: 3, Club: 4 }; The code works fine only JSHint is warning me every time. When relying upon ECMAScript 6 features such as const , you should set this option so JSHint doesn't raise unnecessary warnings. /*jshint esnext: true */ ( Edit 2015.12.29 : updated syntax to reflect @Olga's comments ) /*jshint esversion: 6

JSLint is complaining that (true) is a weird condition . Which is understandable if I wasn't using it on a reversed switch statement. So is JSLint wrong or should I not be using reversed switch statements? Thanks for any help/enlightenment. switch (true) { case (menuLinksLength < 4): numberOfColumns = 1; break; case (menuLinksLength > 3 && menuLinksLength < 7): numberOfColumns = 2; break; case (menuLinksLength > 6 && menuLinksLength < 10): numberOfColumns = 3; break; case (menuLinksLength > 9): numberOfColumns = 4; break; default: numberOfColumns = 0; } The third edition of the ECMA-262

The array.prototype.reduce function at: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce It has the following loop: for (index = 0; length > index; ++index) { if (this.hasOwnProperty(index)) { if (isValueSet) { value = callback(value, this[index], index, this); } else { value = this[index]; isValueSet = true; } } } I don't think there is a difference whether the index is pre or post incremented here since it's done after the loop iterates each time, but want to be certain. Can this be changed to index += 1 so it passes jslint? Please don't debate
