– 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.
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.
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
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.
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.
