[WordPress] 外掛分享： Flying Scripts: Delay JavaScript to Improve Site Speed & Performance

內容簡介

按下使用者互動後下載並執行 JavaScript。

演示影片

Flying Scripts 會延遲執行 JavaScript 直到沒有使用者活動。您可以指定關鍵字以包含延遲執行的 JavaScript。還有一個超時時間，在沒有使用者活動時會執行 JavaScript。

為什麼要使用這個外掛程式？

JavaScript 很佔資源。延遲執行非關鍵性 JavaScript（不需要於初始渲染）可讓您優先處理並為關鍵性 JavaScript 檔案提供更多資源。這樣您就可以減少渲染時間、互動時間、第一次 CPU 空閒、最大潛在輸入延遲等。同時，透過減少請求數量，也可以減少瀏覽器的初始數據負載。

原文外掛簡介

Download and execute JavaScript on user interaction.
Demo video
Flying Scripts delay the execution of JavaScript until there is no user activity. You can specify keywords to include JavaScripts to be delayed. There is also a timeout which executes JavaScript when there is no user activity.
Why should I use this plugin?
JavaScript is very resource-heavy. By delaying the execution of non-critical JavaScript (that are not needed for the initial render), you’re prioritizing and giving more resources to critical JavaScript files. This way you will reduce render time, time to interactive, first CPU idle, max Potential input delay etc. This will also reduce initial payload to browsers by reducing the no. of requests.
