About JS's function. From Baidu to know the answer, study.

In JS, the syntax for creating a function object is var myFunction = new Function (arg1,..., agrn, body);
where the n parameters of the function object are placed in front of the body of the function body parameter, that is, the function body parameter must be placed at the end of the parameter list, or there can be no parameter new function (body).
If you add a third parameter to the last, then "alert (x+= ' aasf ')" will be passed into Func as a parameter, and the third parameter you add becomes the body of the function principal parameter, and there is no interaction between the parameters, of course, there will be no running effect.

It is often used, but it is not clear what the detailed definition is.
