Course Introduction:The Chinese meaning of this is "current; this". It is a pointer variable in JavaScript, which points to the running environment of the current function. When the same function is called in different scenarios, the pointer of this will change, but it will always point to the real caller of the function in which it is located; if there is no caller, this will point to the window.
