To check whether the target site depends on JavaScript, it is best to ask the developer if it is your own site, or directly to the customer if it is a customer site. If you're not sure, try disabling JavaScript in your browser or using an extension like Quick Javascript Switcher to turn off JavaScript before viewing the site. If you view a site that relies on JavaScript with JavaScript disabled, the screen will be blank or only some content will be displayed. Even if all the content is displayed on the top page, be aware that some content may depend on JavaScript, such as product and article lists, recommendation blocks on detail pages, etc. When a site that relies on JavaScript is crawled with the default settings, in the case of a SPA, only the top page and a few discovered resources are displayed, and the crawl is complete, as shown in the example below.
If only part of the site (for example, a product list on an e-commerce site) relies on telephone number list JavaScript, the URLs detected from the original HTML will be listed, and those that depend on JavaScript will not be displayed in the list.

However, there is a reason why JavaScript rendering is turned off by default. Understand why before you turn it on. A crawl with JavaScript enabled retrieves and renders all the resources on each page, so it retrieves more resources than a regular HTML crawl. This may not have much of an impact on small sites, but for medium-sized sites or larger, the load on the server and crawl time will increase significantly. Therefore, it is a good idea to crawl websites that do not rely on JavaScript using the default settings. Preparing to crawl JavaScript By turning on JavaScript crawling in Screaming Frog's settings, you can use Chromium's rendering engine to render HTML before crawling links.
