When you’re working on creating any type of content through JavaScript you want to be sure that you don’t have coding mistakes. Those mistakes, even minor ones, could cause a lot of problems for your system and could mean that you end up with an end product that doesn’t even work. So, you want to locate the mistakes before you try to put your updates live (or even as you’re working). But how do you manage that?

Top Options

The truth is there are a lot of different systems and options when it comes to finding mistakes in JavaScript. These include JSHint, ValidateJavaScript, and JavaScript Validator. Each of them will provide you with high-quality output so you know what you’re getting and whether or not your coding is going to work when you actually make it live. But let’s take a little closer look at each of them.

JSHint

This system is great because all you have to do is go into the website and you can directly input your JavaScript code. When you do, you’ll see automatic updates on the side of the page that will let you know what you have and whether you have any mistakes. What you won’t get is a lot of extra filler on the page because this website is designed to do one thing and one thing only.

If your goal is only to look at the script you’ve created and get immediate feedback then you’re definitely on the right track here. Check it out for yourself to see how it’s going to work and to try it with some of your own codings.

Validate JavaScript

With this website, you’re going to get another simplistic design, though it looks a little different. You’ll get a simple box that you can copy and paste your content into. Once you do, you can select for the system to find errors and even to automatically fix some of them for you. Or each of your errors will be displayed in a list format so you can take a closer look and see what needs to be done for each of them.

You’re going to get a good layout of each of your errors in the order, so you know where they are and what they are and then you can make sure that you don’t miss any. The most important thing is definitely that you can speed up your process and keep checking your errors as needed. Check it out here to see if it will work for you.

JavaScript Validator

Use this website to copy and paste your content and then check and see how your JavaScript code is doing. You can even edit in real-time and continue updating the errors that are listed in your code. The great thing is that the design is simple and actually highlights the different syntax errors that you might have. From there, you can make the changes you want directly in the system and you can move on to the next one.

If you’re looking for a way to make your JavaScript code easier to read and make sure that you’re not missing some of the simple errors (or the more complex ones) you’re definitely going to want to take a look at this system.

What You’re Looking For

When it comes to a JavaScript mistake finder you want to make sure that you have something that’s easy to use and definitely something that’s going to give you all of the information that you need, but you may want to take a closer look at some other factors too.

Easy to Use – First, you want to make sure that you can copy and paste your code directly into the system. This is going to be a lot easier than uploading a file or having to retype the code into the box. Once you write it up in a different platform (which is how you’re likely going to do it) you want to be able to transfer it quickly and all at once.

Easy to See Errors – Next up, you need to be able to see the errors quickly and easily. This could be in the form of a list like some of the options do or highlighting errors directly in the code so you can see them. Which format is easier for you will be up to you, but these will generally make it easier for you to make updates quickly and not miss anything.

Repeated Use – You should be able to either make updates directly in the box and see real-time changes to your error list or rerun the test as often as you want to make sure that you’re getting the problem fixed. This is going to make it possible for you to create the level of code that you’re looking for.

Variety of Errors – Make sure you know what kind of errors your system is going to check. The more types of errors that you check the better it’s going to be because you can get even more problems out of the way quickly before they become a more serious problem. Make sure you know if your system is only checking for basic or fundamental errors or if it can find more complex (or vice versa).

Conclusion

When it comes down to it, you want to make sure you have a high-quality JavaScript checker that will help you create a high-quality system. You want your code to look great when it’s done. And you want it to function the way you would expect. The only way to make sure of that is to make sure that you’re running a check with a mistake finder (or two if you really want to be sure).

While there are some paid services out there, you can absolutely take a look at these free services to see what they find and make your updates and improvements based on them.
