Write Code Like the Pros


So, you want to write code like the pros? I’m going to outline the exact habits that have helped me, a professional software developer at Google, since I began my career in 2006.

The first thing you should do is always indent your code. This will make it much easier to read and understand. Spaces are preferred over tabs, but it’s up to you.

The second thing you should do is always use semicolons. This will prevent ASI from happening and cause bugs due to some unclear edge cases.

The third thing you should do is always use curly braces for if-else statements even though they are optional because it will make your code easier to navigate and understand for other people who may or may not be as intelligent as you are.

The fourth thing you should do is always use loops instead of recursion because recursion takes up too much memory and can cause stack overflows in large inputs that may or may not occur depending on your algorithm and input size (which could be anything).

The fifth thing you should do is always use while loops instead of for loops because while loops are more efficient than for loops in most cases where efficiency matters (which could be anything).

The sixth thing you should do is always use === instead of

The linter is a tool that analyzes your code and looks for mistakes. It is much like a spell checker. It will not correct your mistakes for you, but it will point them out and give you some suggestions on how to fix them.

The linter we are going to use today is called jshint. This is the same tool used by companies like Twitter and jQuery, so it’s pretty popular in the JavaScript community. There are plenty of other tools out there, but this one seems to be the most popular.

JSHint, a JavaScript Code Quality Tool

Report Cyclomatic complexity Unused variables Undeclared variables.

JSHint is a community-driven tool to detect errors and potential problems in JavaScript code and to enforce your team’s coding conventions. 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.

It is open source and will always stay this way. Please feel free to report any bugs, feature requests or other issues.

Please note that we are not going to add support for non-standard language extensions at least until they become widely implemented across JavaScript engines. Also, we believe that allowing certain problems in the code (like unused variables) will only make things worse, so don’t expect us to remove warnings just because some people think that they are useless or annoying.

JSHint is an open source tool that helps to detect errors and potential problems in your JavaScript code. It does basic syntax checking as well as applying a set of rules to the code that look for problematic patterns or signs of inefficiency. The rules are from the book “JavaScript: The Good Parts” and have been tuned to discourage bad practices and prefer good coding conventions.

The easiest way to use JSHint is through our web-based interface at jshint.com. Just copy and paste your code into the box below and click “JSHint”.

If you are using Node, you can install a command line version of JSHint called jshint-cli. To do so, run npm install -g jshint-cli.

Once installed, invoke it like so: $ jshint myfile.js

JSHint will then print out any possible issues with the code onto your console. If no errors were found, then a success message will be printed out on the console.

JavaScript is the most popular programming language on earth, but it has a bad reputation among developers.

Some of the reasons for this are:

– JavaScript has no compilation or typing system

– It’s difficult to write large programs in JavaScript

– It’s hard to find good JavaScript programmers

JavaScript is finally growing up, though. This is due in part to the rise of AJAX and other technologies that force developers to write more complex applications in their browsers. Fortunately, there are new tools that help us leverage the power of JavaScript without getting burned by its quirks. Among these tools is JSLint, a program that checks JavaScript code for suspicious syntax and bugs.

JSHint is a static code analysis tool used in software development for checking if JavaScript source code complies with coding rules. It is provided with some predefined defaults, but can be configured to enforce additional rules.

It was created to detect errors and potential problems in JavaScript code and to enforce coding conventions. The project was originally named JSLint and was developed by Douglas Crockford.[2] In 2013, Anton Kovalyov took over the project, renamed it to JSHint and moved it to GitHub.[3] JSHint is available as a command line interface or as a plugin for text editors like Eclipse, Vim, TextMate, Sublime Text,[4] IntelliJ IDEA[5] and others. It can also be used programmatically through an Application Programming Interface (API).

JSHint is a program that flags suspicious usage in programs written in JavaScript. The core project consists of a library itself as well as a CLI program distributed as a Node module.

JSHint was created by Anton Kovalyov (aka valueof), who later handed the project to Mike Sherov (aka msherov).

JSHint is currently maintained and developed by Anton Kovalyov, Mike Sherov, and other contributors.

If you think you’ve found a bug in JSHint, please open an issue on GitHub. If you have a patch, please feel free to send us a pull request.
