Javascript中==和!=的规则？

Question

下面整理的这个表有什么问题吗？

注：Primitive()代表valueOf()|toString()

比如：'1' == new Number(1) 会先调用new Number(1)的valueOf，如果可以直接做全等比较就直接做，如果不行就再调用toString()转为字符串做全等，如果还不行，就将‘1’和toString后的字符串转为数字再比较，不全等就为false，全等就为true

我的理解对吗？

下面是小于（<）、大于（>）、小于等于（<=）和大于等于（>=）这几个关系操作符的隐式转换规则，也贴出来了，辛苦大家看一下，有问题，请指出，感谢！

Answer 1

看一下这篇文章聊一聊valueOf和toString

Answer 2

==

The comparison x==y, where x and y are values, produces true or false. Such a comparison is performed as follows:

1. If Type(x) is the same as Type(y), then

   1. Return the result of performing Strict Equality Comparison x===y.
2. If x is null and y is undefined, return true.
3. If x is undefined and y is null, return true.
4. If Type(x) is Number and Type(y) is String, return the result of the comparison x == ! ToNumber(y).
5. If Type(x) is String and Type(y) is Number, return the result of the comparison ! ToNumber(x) ==y.
6. If Type(x) is Boolean, return the result of the comparison ! ToNumber(x) ==y.
7. If Type(y) is Boolean, return the result of the comparison x == ! ToNumber(y).
8. If Type(x) is either String, Number, or Symbol and Type(y) is Object, return the result of the comparison x==ToPrimitive(y).
9. If Type(x) is Object and Type(y) is either String, Number, or Symbol, return the result of the comparison ToPrimitive(x) ==y.
10. Return false.

Answer 3

== 会隐式转换类型
=== 类型和值完全相同 才是全等
