What makes a function anonymous in JavaScript?

Question

Are constructor functions anonymous

Answer 1

Anonymous functions are the ones without a name that cannot be called.

var anon1 = function(){};
//This function does not have a name, you can only call it if you assign it in a variable like so.

Also, arrow functions are always nameless.

Answer 2

To add to Valen.H. ~ 's great answer, you can call a nameless function without assigning it but you can't reuse it!
function(){}(); should work

edit: no it don't!
but (() => alert("toto"))() does!

Answer 5

Thanks for the solution ..I'll try it even though I'm still trying to wrap my head around your answer

Answer 6

Sorry I didn't read your comment. To answer you, the error is that you don't call person, you assign the result of a "function(){}()" like expression to person, but this expression is invalid. You can store function(){} in a variable then call it.

To sum it up

function(){}
- can be stored
- can be used only if stored

() => {}
- can be stored
- can be called even if not stored
