这个脚本到底做了什么？

Question

所以我一直试图了解https://rblx.trade/catalog/deals （一个实时跟踪 roblox 目录并将更改传达给客户端的站点）如何与客户端通信。 为此，我一直在检查该站点并看到了这个脚本，我认为它是向客户端传达新数据的脚本。

<script id="__NEXT_DATA__" type="application/json">
                {
                  "props":{
                    "pageProps":{
                      "title":"Roblox Catalog Deals","meta":{"description":"Get the best deals and snipes on Roblox limited items with our deals page! Also turn on notifications to get notified immediately whenever an item gets put up for sale for a cheap price on the Roblox catalog!"}
                      },
                      "__N_SSG":true},
                      "page":"/catalog/deals","query":{},"buildId":"WlqGtyKoC3mZ3T4hTYU5G","runtimeConfig":{
                      "isStaging":false,"api":{"url":"https://rblx.trade","proxyFrontend":false},"sentry":{"dsn":"https://cbbd6a053f7a4d8b8a182804421dddad@sentry.rblxtrade.com/3","tracesSampleRate":0.01}
                      },"isFallback":false,"gsp":true,"scriptLoader":[]
                }
    </script>

问题是不知道它是怎么做的以及它是如何工作的，因为我不知道 javascript。 我搜索了一些脚本类型的工作原理以及 dns 的含义，但就是这样。 任何帮助理解这个脚本的作用都会很棒

This is not completely Javascript, as you can see in the type type="application/json" its JSON , JSON is a notation to write objects in javascript. 脚本本身不做任何事情，只是定义了一个信息结构。 可能使用此信息的逻辑在其他地方
