解码用到了新的 ArrayBuffer / TypedArray API
传统的 Message 化控制流扩展
WebExtensions ContextMenus API
常见的 BrowserAction
还有许多不能直接发上来了，只有简化版，待会还有一个 time limited cache，看看。

开始我还以为是自动构造数学表达式然后 filter 呢……GitHub

为什么js没有array初始大小和扩容的概念? - 知乎
在谈论js时，很少听人谈论array，object等引用型数据类型初始大小以及扩容的问题？这是为什么？也没有听…
function* readSourceTable(text) { //< obsoleted
let entries = text.split("\n\n");
for (let entry of entries) {
let entryList = [];
let key = null; let content = "";
for (let line of entry.split("\n").map(it => it.trim())) {
if (line.length == 0) continue;
if (line.endsWith(":")) {
if (key != null) entryList.push([key, content]);
key = line.substring(0, line.length-1); content = "";
} else content += `${line}\n`;
}
entryList.push([key, content]);
yield entryList;
}
