Detailed explanation of js anonymous function usage and parameter passing examples

The following editor will bring you an article on using js anonymous functions & passing parameters (examples). The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor and take a look.

As shown below:

##

function () { alert("error"); } //报错：匿名函数不能直接调用

Use

(function () { alert("Success"); })()//直接使用

##

var anonymous=function () { alert("success"); } anonymous();//赋值调用

0x01

(function (m,n) { return m+n; })(10,20)//直接使用

var anonymous=function (m,n) { return m+n; } anonymous(15,20);//赋值调用
