就是object，它是原生对象，他能够new一个实例。

Answer 2

写了代码测试了下
<script>
document.write ("typeof(1): "+typeof(1)+"<br>");
document.write ("typeof(NaN): "+typeof(NaN)+"<br>");
document.write ("typeof(Number.MIN_VALUE): "+typeof(Number.MIN_VALUE)+"<br>")
document.write ("typeof(Infinity): "+typeof(Infinity)+"<br>")
document.write ("typeof(\"123\"): "+typeof("123")+"<br>")
document.write ("typeof(true): "+typeof(true)+"<br>")
document.write ("typeof(window): "+typeof(window)+"<br>")
document.write ("typeof(document): "+typeof(document)+"<br>")
document.write ("typeof(null): "+typeof(null)+"<br>")
document.write ("typeof(eval): "+typeof(eval)+"<br>")
document.write ("typeof(Date): "+typeof(Date)+"<br>")
document.write ("typeof(sss): "+typeof(sss)+"<br>")
document.write ("typeof(undefined): "+typeof(undefined)+"<br>")
</script>
结果如下
typeof(1): number
typeof(NaN): number
typeof(Number.MIN_VALUE): number
typeof(Infinity): number
typeof("123"): string
typeof(true): boolean
typeof(window): object
typeof(document): object
typeof(null): object
typeof(eval): function
typeof(Date): function
typeof(sss): undefined
typeof(undefined): undefined
