 Other times, it's less obvious though. Content can appear to be static (non-dynamic) when it is not, or even sometimes the other way around.

 If JavaScript is enabled - clicking the button will switch it off and reload the page. The next click will re-enable JavaScript and refresh the page. This extension is useful for checking whether a certain website will work without JavaScript (and thus could be parsed without using a browser with a plain HTTP request) or not.

 ## Making the choice {#making-the-choice}
 
-When choosing which scraper to use, we would suggest first checking whether the website works without JavaScript or not. Probably the easiest way to do so is to use the [Quick Javascript Switcher](../../glossary/tools/quick_javascript_switcher.md) extension for Chrome. If JavaScript is not needed, or you've spotted some XHR requests in the **Network** tab with the data you need, you probably won't need to use an automated browser browser. You can then check what data is received in response using [Postman](../../glossary/tools/postman.md) or [Insomnia](../../glossary/tools/insomnia.md) or try to send a few requests programmatically. If the data is there and you're not blocked straight away, a request-based scraper is probably the way to go.

 It also depends of course on whether you need to fill in some data (like a username and password) or select a location (such as entering a zip code manually). Tasks where interacting with the page is absolutely necessary cannot be done using plain HTTP scraping, and require headless browsers. In some cases, you might also decide to use a browser-based solution in order to better blend in with the rest of the "regular" traffic coming from real users.

 ## How different is TypeScript from JavaScript? {#how-different-is-it}
 
-Think of it this way: Javascript **IS** Typescript, but TypeScript isn't JavaScript. All JavaScript code is valid TypeScript code, which means that you can pretty much turn any **.js** file into a **.ts** file and it'll still work just the same after being compiled. It also means that to learn TypeScript, you aren't going to have to learn a whole new programming language if you already know JavaScript.

 What are the differences? Well, there's really just one: TypeScript files cannot be run directly. They must first be compiled into regular JavaScript.
