List all built-in functions in javascript?
提问by Frawr
Is there a way in js to list all the builtin functions and some info on their parameterlists? I couldn't really find anything about reflection to do this sort of thing
js 中有没有办法列出所有内置函数及其参数列表中的一些信息？我真的找不到任何关于反射的东西来做这种事情
edit: The functions such as Math.sin are actually the ones I want to list, actually all built-in functions.
编辑：Math.sin等函数其实就是我要罗列的，其实都是内置函数。

Something like this, maybe?
像这样的东西，也许？
for( var x in window) {
if( window[x] instanceof Function) console.log(x);
}
This will list all native functions in the console (excluding one in native objects, such as Math.sin()).
这将列出控制台中的所有本机函数（不包括本机对象中的一个，例如Math.sin()）。
