JSHint is a program that analyzes JavaScript code for common mistakes. It is a static analysis tool, which means that it analyzes your code without executing it. In this article I will show you how to integrate JSHint in to your development process and why you should be using it.
Why Use JSHint?
It’s simple, JSHint can save you time and make you a better developer. A lot of developers think that linting tools are a waste of time, since they can already debug their own code, but that’s not the point! It’s not about being able to detect errors in your code, it’s about being able to detect them faster and more efficiently. It’s about improving your development workflow by integrating static analysis in to it.
JSHint is a tool that helps to detect errors and potential problems in your JavaScript code. JSHint does this by looking at some of your code’s more subtle aspects, like for example scoping. It then reports back to you with a list of errors and potential problems.
The goal of JSHint is to help JavaScript developers write complex programs without worrying about typos and language gotchas. To do this, it warns about the bad parts of JavaScript, enforcing a “good parts” subset.
I’ll be honest, I don’t like JSHint very much.
JSHint is an open source tool for detecting errors and potential problems in JavaScript code. It is widely used by developers to detect problems and enforce coding standards.
The main advantage of using JSHint is that your code will be more reliable, understandable and maintainable – the three most important traits of good software development.
JSHint is a great tool for making sure that you write quality code, but it can also be used to enforce coding standards within your development team. You can easily setup JSHint with Grunt to make sure that every developer on your team adheres to the same rules and conventions.
JSHint is a static code analysis tool for JavaScript that helps to detect errors and potential problems in your source code. It is built on top of JSLint, which was first released in 2002 by Douglas Crockford.
What makes it so special?
It is more flexible than JSLint and can be configured to suit your needs. It supports the latest version of JavaScript, including ECMAScript 5 (ECMA-262) and ECMAScript 6 (ECMA-262).
It detects errors and potential problems and immediately provides you with warnings.
The warnings are not limited to syntax-related issues, but also include semantic problems. For example, JSHint will warn you if you use an assignment expression in a conditional statement or if you declare or access variables outside their intended scope.
It has an online version where you can test your code. You can also install it as a browser extension for Chrome and Firefox, or as a Node package (for Grunt users).
Every developer who has ever worked on a JavaScript project has probably encountered the following scenario: you’re working on a new feature, and right before you commit your changes you decide to run your code through JSLint to make sure everything is kosher. You do this because writing good JavaScript is hard, and it’s easy to introduce syntax errors that won’t be caught until runtime (if they’re caught at all).
You run JSLint and immediately see that something isn’t right. There are a ton of errors, many of which seem unrelated to your feature or the code you’ve changed. You ignore them for now, but later when you come back to the project these errors will still be there, staring at you in the face every single time you try to commit new changes. You don’t want to fix these errors because they’re not related to your work, but at the same time it doesn’t feel right committing new code with these errors in place.
JSHint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules. Use of such tools is essential for finding errors and avoiding “works on my machine” situations.
JSHint has a lot of options that let you customize it to your own style guide, which makes it the best tool for enforcing your team’s conventions. JSHint can be easily added to projects’ build system or continuous integration environments.
JavaScript is an interpreted language with no compilation step and no types. This makes it harder to write reliable software when compared to statically typed languages like Java or C/C++. JSHint helps developers write more robust code by finding problems before the code runs, not after.
Other than type checking, JSHint flags some problematic JavaScript patterns that might lead to unexpected results such as:
– Unused variables
– Undeclared variables (implied globals)
– Semicolon insertion (ASI)
– Strict mode violations
– Trailing whitespace found (“trailingspaces”)
– Expected an assignment or function call and instead saw an expression (“experession”)
