JavaScript Linting should be done. Here’s a few reasons Linting is important:

– The first reason is that it helps you reduce your code size. Most of the time, you may not have to use semi-colons in JavaScript, but if you do not add them and forget to add them in other places, this can cause your code to break. Linting will help you find those errors.

– The second reason is that it helps you find syntax errors in your code. For example, if you forget to close a parenthesis and linting is enabled, the linter will tell you that there is an error in your code.

– The third reason is that it helps you write code faster. Because most linters will auto fix some of the errors for you and give you suggestions on how to fix other problems, this will save a lot of time for developers who are working on very large projects.

– The fourth reason is that it helps prevent bugs in your code. Most bugs are caused by syntax issues which linters can catch early before they cause any issues with your application.

JSLint is a static code 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 http://www.jslint.com, and is also distributed as a command-line application and an optional plug-in for Microsoft Visual Studio.

JavaScript Linting should be done. Here’s a few reasons Linting is important:

Consistency of Style – This can be especially important on large projects where the style can get away from you. This becomes even more important when working with others, or on a team. You want to make sure everyone is writing similar code, so that when someone else needs to edit your code, they don’t get lost in it.

Missing Semicolons – Semicolon are not necessary in JavaScript but missing them can cause some very difficult to find errors, and are generally good practice to have in your JavaScript so you know where the end of an expression is. This can be especially useful when you have multiple lines of code all on one line, and you forget to add a semicolon at the end of each line. This will cause JavaScript to think that the two

JavaScript Linting should be done. Here’s a few reasons Linting is important:

1. Code Consistency

2. Error Catching

3. Prepares your code for minification

4. Easy to read code

5. Find potential problem areas in your code

6. Makes working with other developers easier that use the same Lint ruleset as you do

JavaScript Linting tools are abundant and vary by development environment (IDE), operating system, and browser. Most modern IDE’s have JavaScript linting built in or available as an addon plugin, which is the easiest method of using one of these tools. The downside is that if you work on multiple platforms this may not be an option for you. You can also use browser based linter’s like http://www.jslint.com/. This works great if you primarily develop on a single operating system and prefer to use the same browser for your development and testing, which I do not recommend doing (See my previous post on why). Once you find a tool that suits your needs it becomes very simple to integrate it in your workflow and begin reaping the benefits of having your code linted

JavaScript Linting should be done. Here’s a few reasons Linting is important:

1.)It will help you find Syntax errors

2.)It will help you find “Best Practices” issues (i.e. putting code in the global scope)

3.)It will help you find variable and function declarations that are never used again

4.)It will help you find potential issues with “Strict Mode”

5.)It will help you find issues like “==” vs “===”, which is an important difference if you care about your code

6.)It saves time by catching these errors sooner rather than later

7.)It helps keep code clean, consistent and easier to read for other developers (or even yourself after some time away)

First of all, just like spell check, linting finds syntax errors. Now, I’m not talking about syntax errors that will cause your code to crash or throw an error, but syntax errors such as missing semicolons, bad spacing or indentation and misspelled words. These are the type of things that are harder to find when you have hundreds or thousands of lines of code.

Linting is also important because it can enforce coding style and standards. This can be very helpful in teams of developers or even when working alone on larger projects.

Lastly, it can catch some potential bugs as well. For example, if you leave off a closing bracket ‘}’ in an if/else statement, a linter will pick this up and help you avoid a bug later on.

For these reasons and more it’s a good idea to start using JSLint today.

The purpose of JavaScript Lint is to detect suspicious usage in JavaScript programs.

The more programs you write, the more likely it is that your programs contain bugs. The more bugs you encounter, the more time you spend looking for them. JavaScript Lint can save you time by encouraging proper programming practices and locating errors for you.

JavaScript Lint will perform a check on your code, and find common mistakes or warnings that may lead to errors in the future. These could be anything from missing semicolons to incorrect variable names. It’s best practice to lint your code before running it in production, so that you catch any mistakes early on and before they make their way into production.

JavaScript Lint reduces debugging time. When your program works perfectly the first time, then you are very lucky. In most cases, you need to lint your code constantly in order to perfect it. Linting makes it easier for others to read your code.

Help avoid potential errors when writing code. JavaScript is a loosely typed language, which means you don’t have to declare a variable before using it and you don’t have to declare the type of data that will be stored in the variable. This can cause problems when writing code, as you may be referencing variables that haven’t been declared yet, or you may be trying to use a method on a variable that doesn’t exist. JSLint helps identify these problems before they occur in real life scenarios.

Help improve code readability and organization. As your code base grows, it becomes harder and harder to find the exact function that you’re looking for. If your functions are named properly and organized into objects, this can help alleviate some of the pain. JSLint forces you to use proper naming conventions for variables and methods (camelCase) as well as organize your code into objects.

Consistency across developers. If everyone on your team is using JSLint, then your entire code base should look relatively similar. This makes adding new developers to the team easier because they won’t have to get accustomed to a whole new set of coding standards and habits that each developer has adopted over time.
