Function as Parameter in another Function

Hi everybody. Please help with such problem

For example. We have
function1 (param1, param2, param3)
{
Block working with Parameter 1
Block working with Parameter 2

If (Parameter 3 === 1) {function2()}
If (Parameter 3 === 2) {function3()}
}

My question.

Is it possible send function (or function name or something) as parameter

Something Like this:

function1 (param1, param2, param3)
{
Block working with Parameter 1
Block working with Parameter 2

param3_funct
}

Call from Program Body

function1(eact_param1_1, exact_param2_1, function2)
or
function1(eact_param1_2, exact_param2_2, function3)

When I tried to do this I received error
finction2 and function3 started immediately after call
before function1 started, beforу Block working with Parameter 1 and 2

OK. I repeat my question
Is It Possible Such Call function as parameter or not

Thank You in advance
Sincerely Mikhail

Should be pissible…

Are you searching for something like this? (for example)
x + y * z = ??? ( 23? )
Then 23-22 = ??? —> ( 1 ? )

You need ASYNC-AWAIT

$w.onReady(async function () {
 let x = 3;
 let y = 4;
 let z = 5;

 let RESULT = await myStartFunction(x,y,z);
    console.log(RESULT)
    start_secondResultFunction(RESULT)
})

function myStartFunction(x,y,z) {
 return (x+y*z)  
}

function start_secondResultFunction(RESULT) {
    console.log(RESULT-22)  
}

Take a look onto your CONSOLE!

Sure, you can pass a function as the parameter of a function. This usage is very common for passing a callback function.

Doing an Internet search for “javascript pass function as parameter” turns up 38.200,000 results. I’m sure you can find what your looking for.

Can you make a simple example? My example was not really the right one?

Thank You very much

Now my code working.

My mistake was here:

function addStudent ( id , refreshCallback ){ refreshCallback ();}

I forget about “()” after “parameter function name”
