.bind 是一个普通的函数，所以你可以在上面调用 .apply .
您所要做的就是将原始函数作为第一个参数传递，并将所需的 THIS 变量作为参数数组中的第一项:

.bind is a normal function, so you can call .apply on it.
All you have to do is pass the original function as the first param and the desired THIS variable as the first item in the array of arguments:

bound = db.find.bind.apply(db.find, [null].concat(arguments));
//      ^-----^            ^-----^   THIS

这是否可以被认为更清晰由读者决定.

Whether that can be considered cleaner or not is left to the reader.
