先前在《開源應用程式架構》一書中，我介紹了 SocialCalc 這個在瀏覽器中運行的試算表編輯器，以取代伺服器為中心的 WikiCalc 架構。SocialCalc 在瀏覽器中執行所有的運算，只有在載入和儲存試算表時才會使用伺服器。

追求效能是 Socialtext 團隊在 2006 年時設計 SocialCalc 的主要目的。重點在於：在 JavaScript 環境下執行客戶端運算，儘管在當年的速度僅有伺服器端 Perl 運算的十分之一，但仍然勝過 AJAX 來回傳輸資料造成的網路延遲：

	Super Form Reset

	A couple of things to watch out for:

	- IE8: If a text input doesn't have padding on all sides or none the text won't be centered.
	- The default border sizes on text inputs in all UAs seem to be slightly different. You're better off using custom borders.
	- You NEED to set the font-size and family on all form elements
	- Search inputs need to have their appearance reset and the box-sizing set to content-box to match other UAs
