How to deal with anonymous functions in javascript functions?

Functions in JavaScript are first-class members which means that you can work with them just as you would any other data type in the language - you can pass them as arguments, keep them as member variables inside of other functions, return them from functions etc In the case you've asked about, it works just like any other named variable with the neat addition that you can invoke the function as below since it is a function: function myFunc(anonymous){ var arg1; anonymous(arg1); } myFunc(function(arg1){console. Log(arg1)}).

Just call it using the name of the parameter. Function callThisLater(laterFunction) { // ... laterFunction(args); } callThisLater(function (arg1) { alert("We've been called! "); }).

Here is basic example: function Foo(func) { this. Func = func; this. Activate = function() { this.Func(); }; } var foo = new Foo(function() { alert("activated"); }); foo.Activate(); I believe that what you missed is using the () to "activate" the function - as far as I understand you reached the point of "storing" the function to variable.

Can you assign your anonymous function passed as an argument to a named function to a global variable inside the named function and then can used the global variable as a reference to anonymous function.

So you're not talking about global variables then, since it's a variable inside a function. That should probably be edited so it's not confusing. – no.good.at.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
