Write Code the Right Way with this Easy JavaScript Linter


I just read an interesting post on the JavaScript Lint blog (that is, a blog about errors and mistakes you make in JavaScript) that I thought was worth sharing. Titled “Why would I want to use JSLint?”, it summarizes the various reasons why someone might want to use JavaScript Lint in their development process:

JSLint looks for the bad parts of your program and helps you avoid them.

JSLint helps you to follow good coding style.

JSLint helps you to write more maintainable code.

JSLint can check for common coding mistakes.

JSLint can detect potential problems in your code that may cause it to fail when it is run on other browsers or platforms.

JSLint will make sure that your code works in all versions of JavaScript.

JavaScript Lint is a tool that verifies your JavaScript source code for potential problems and errors. It scans your source code looking for specific patterns of usage — such as undeclared variables — and warns you if it finds any matches. The basic idea behind JSLint is simple: if there’s a problem with your code, you should know about it before you deploy it into production.

When you write JavaScript code, there are some errors that can only be discovered during runtime. This means that you will have to test your code before deployment. However, that isn’t the only way to discover potential issues in your code. There are tools such as ESLint and JSHint that can check your source for common mistakes and help you find them before you even run your script.

JSHint is a tool that helps to detect errors and potential problems in your JavaScript code. It is very flexible so you can easily adjust it to your particular coding guidelines and the environment you expect your code to execute in.

The main reason why I like JSHint is because it catches sloppy coding habits that I make all too often — like missing semicolons or forgetting var declarations — and best of all, it’s completely customizable. You can choose which rules are applied when linting your JavaScript code and also specify global variables that should be ignored.

JSHint is a tool that helps to detect errors and potential problems in your JavaScript code. The core project consists of a library itself as well as a CLI program distributed as a Node module.

The problem

JavaScript is a very flexible language which provides great power to the programmer, but with this power comes responsibility in terms of code quality. An increasing number of large projects use JavaScript and keeping the code base manageable becomes more and more important. JSHint takes this responsibility from you by analyzing the source code for problematic patterns or if any of the predefined rules are violated.

You write code. Maybe you’ve made a mistake, maybe not…

But can you be sure?

jshint is a tool that helps to detect errors and potential problems in your JavaScript code. It is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules.

Most editors these days come with JSLint or JSHint built-in so you can see right away if there are any issues with your code. If you’re using Sublime Text, you can install SublimeLinter and SublimeLinter-jshint to get real time feedback on your code.

JSHint is a tool that helps to detect errors and potential problems in your JavaScript code.

The goal of this tool is to allow JavaScript developers from all over the world to create their own linting rules and share them with other developers.

It can be used on the command line as well as on a web site, it works on both Node.js and Rhino, and it can easily be integrated into any build system you might already have.

JSHint is a static analysis tool used in software development for checking if JavaScript source code complies with coding rules. It is provided primarily as a browser-based web application accessible through the URL JSHint.com, but there are also command-line adaptations.

JSHint was created by Anton Kovalyov and first released in 2011. It is a fork of the older project JSLint by Douglas Crockford, which began in 2002 and has been updated since, but without official releases or documentation. While JSLint is not open source software, most of its core functionality has been made available as part of the open source JSHint project.

JSHint can be run within web browsers or from the command line. The web version allows one to check their code using default options or using settings chosen by the developer. The command-line version can be installed on Unix, macOS, and Microsoft Windows via npm.

JSHint (by default) defines a number of “globals” that are commonly used by JavaScript libraries. These are things like window , document , undefined , and many others.

By default, JSHint considers any reference to an undeclared variable to be an error. If you would like to allow such references, use the /*global */ directive at the top of your file to tell JSHint about them. For example:

/*global $: false, jQuery: false */

$(document).ready(function() {

// …

});
