我寫了一個html頁面，代碼如下。<html><header> <div class="logo"><a href="index.html" title="Coyle Appliance Repair"></a></div> <div class="phoneNumber"><h3 class="numberHeader">call today for an appointment - same day service is available</h3> <h1 class="number"><a href="tel:+1-555-555-5555">555-555-5555</a></h1></div> <div class="greyStrip"><h2 class="motto">Serving the Twin Cities and western Wisconsin since 1982</h2></div></header><script> ((function demo () { let a = 1 while (a < 10000) { a++ console.log(a) } })())</script><div class="mainContent"><h2 class="missionStatement">Full service restaurant and commercial kitchen repair. We service all cooking, food prep, warewash/dishroom, and refrigeration equipment.</h2></div></html>問題是，keep和remove代碼有什么區(qū)別console.log(a)當我刪除它時，頁面將流暢地顯示，沒有任何阻塞或閃爍。但是當我添加這個控制臺時，頁面會阻塞一段時間或者閃爍。
控制臺會阻止頁面渲染
