Browser default global $ function

Kri*_*ket 2 javascript browser jquery

I've noticed that there appears to be a global function called $ in some browsers which is NOT jQuery, but I can't seem to find any documentation on it. What is it?

Firefox: 火狐

Chrome: 铬合金

Chrome 和 Firefox 开发工具包括一些有用的快捷方式/帮助程序来在控制台中操作 DOM。

这些快捷方式对于两者都非常相似:$用于 DOM 选择,$0-$4用于“最后 X 选择”等等。
