deno 支持哪些 web 的 api , 这个列表可以在在哪个地方进行查看的？
像 fetch 这样的 API 是支持的，但是使用 FileReader 这个 API 就提示 not defined
可以运行 Object.keys(globalThis) 看一下都有哪些。
> Object.keys(globalThis).join('\n')
console
Deno
queueMicrotask
atob
btoa
clearInterval
clearTimeout
fetch
setInterval
setTimeout
crypto
performance
addEventListener
dispatchEvent
removeEventListener
window
self
onload
onunload
