In this class, I'll explain the difference between scope and context in JavaScript. I'll also help you to understand why scope and context may sometimes feel like the same thing, even though they're not. And I'll also explain how to make better decisions about scope and context when planning your code. The third question that we need to answer is, why is it so important to understand the difference between scope and context in JavaScript? Well, as a developer, you spend the majority of your time doing one of two things, development, or troubleshooting. And when it comes to development, if you have a strong understanding of the difference between scope and context, you'll write code that is cleaner and easier to maintain.

And that's because you'll make better decisions about how to best leverage scope and context in your code. When it comes to troubleshooting. If you understand the difference between scope and context, you'll make the best use of your time and take the right troubleshooting steps. To solve your problem quicker. So later on in this course, we'll talk about how to make better decisions about leveraging scope and context in your code. So right now I just want to focus on troubleshooting.

Let's take a look at a typical troubleshooting workflow. So let's say you have a problem or a bug. Now, in most cases, you discover the bug, and you immediately start taking steps to troubleshoot that problem. And if you don't really understand the difference between scope and context, you might find that your troubleshooting steps are kind of all over the place, one thing leads you to another and one minute you think it's a problem with a variable. And then maybe it's a context problem, because it's a property of an object, but then you're not really sure and it leads you down a different path. And at this point, one thing that's clear is we don't have a very focused game plan and our troubleshooting steps are not really leading us any place in a logical way.

So the problem here is that without a really solid understanding of the difference between scope context, you can find that your troubleshooting could take a long time it could be unfocused, and there's a chance that you may never actually get the problem solved. I think there's a better way to do this. So when you start out with a problem or a bug, if the first thing you do is ask yourself a question, Is this a scope or a context problem? And if you ask yourself that question, but first before you take any troubleshooting steps, if you have the knowledge to answer that question, if you understand the difference between scope and context, and you can answer this question confidently, then you can make the right decision. And once you know the answer to that question, then the troubleshooting steps that you take are more logical, they're more focused, and you can solve your problem much more quickly.

So when it comes to troubleshooting, understanding the different teams scope and context helps you to troubleshoot the problem more easily and it's important When you start troubleshooting a problem, you want to ask yourself a question. Is this a scope or a context problem? So the first step is determining if the problem is a scope or a context problem. The second step is to then take the appropriate troubleshooting steps based on the answer to part one. And when you take the appropriate troubleshooting steps, you'll find that your problems more quickly
