0> = null - > true,0> null - > false,0 == null - > false？

Question

例如在Chrome或Firebug中打开控制台.请尝试以下方法:

console.log(0 >= null); /* true, so let's look closer: */
console.log(0 > null);  /* false, so it's got to be equal, right? */
console.log(0 == null); /* false again?? */

那么,如果0 既不大也不相等,0怎么能大于或等于 0 null？ >= >
