NaCl

基本解释

NaCl and Pepper are the salt-and-pepper of web applications, adding what was missing to a more complete web experience.
NaCl和Pepper是Web應用的增色劑，它們加入了一些缺失的功能，使Web應用更加完整。
Google advertises a performance drop of less than 5% for running NaCl code inside the browser compared to out of the browser.
Google認爲，相比在瀏覽器外運行NaCl代碼，在瀏覽器中運行的性能損失低於5%。
Also, NaCl was intended initially to run on multiple browsers, but it seems that only Chrome will support it because others don’t use Pepper.
同樣，NaCl本來希望能夠支持多瀏覽器，但是現在貌似衹有Chrome將能夠運行代碼，因爲其他的瀏覽器不支持Pepper。
