Wouldn't it be more correct to say that both variables and functions are objects instead of saying that functions are variables?

[yadusolparterre]

Functions don't work like objects, functions ARE objects.

It's one of the things I most like about JS. My favorite thing is being able to store different functions in array elements and hash maps, and then invoke them using array indexing or hash key lookup.

It's also why some people will write "function test() {...}" and others prefer to write "const test = function() {....};"

You have quicky become my go to guy. Wow you are such a good teacher. Thank you so much.

This why in JS they call function is First Class CItizen, because you can pass them, return them. But also this is just beginner friendly to said function is variable, in fact they are Object. "Everything in JS is Object"

[technicalboy]

It's not the passing of a function, but the untidy manner of writing a whole function inside the parentheses.

[letter_m]

that makes much more sense, now, I thought when you call a function it gets executed and the result/return is passed. Now that you and some other peeps here mentioned that a function is an object makes almost everything clear! Thanks!

To any beginners almost everything except primitive data types are objects in JS. That's why you can do stuff like this. Functions are objects, arrays are objects, window is a object and so on

How the hell do you have such perfect hair? We need a haircare tutorial :-)

And objects are passed by reference in javascript. so when you call test2() or test() in both cases you are calling same function, the anonymous function which it's reference was saved in test 1, not two functions with same functionality.

"functions are just variables": Functions can be (and usually are) _assigned_ to variables/defined using a name.
But you can still have things like _anonymous_ functions.
A better clickbaity thumbnail text might be "functions are just objects"
I know you know this, but I needed to vent this upon reading the above title in the thumbnail :P

You are so cool. It's easy to understand the concepts.

[AshtonMotana]

Callback functions are freaken awesome.

"The fact you can pass a function to
another function in javascript is really
confusing to a lot of people"
Me whos been a python dev for 5 years and switched to js my 6th (now in my 7th year): Lies.

The way I think about it, is that everything is a memory address. A function pointer, points towards a memory address, just like a variable (int32_t, char, etc.)

[CC-.]

Yeah I pass functions a lot when making a flexible feature

[EternalDarknessAboveTheBlueSky]

ES6 classes are just functions. Functions are just variables. Therefore, ES6 classes are just variables.

[llemgeta]

Your more clearer than my bootcamp lecturer

Hair is looking thicker each time i watch ur video!

[professoroflogic]

Everything is an object... Even your perfect hair.
