In an earlier article, I mentioned that Boing-Boing had a few issues when they wanted to use @font-face embedding inside their website. In short, the problem was that some fonts look bad on computer monitors without font-smoothing enabled in the

原文(被牆):http://www.2ality.com/2012/06/dense-arrays.html 一般來說,JavaScript中的數組是稀疏的,也就是說,數組中的元素之間可以有空隙,因為一個數組其實就是一個索引值映射.本文解釋了如何建立稀疏數組和不稀疏的數組. 1.稀疏數組建立一個指定長度的稀疏數組很簡單:> var a = new Array(3);> a[ , , ]> a.length3>
