Node.JS - Call a Pre-Defined Function in Another Function

I have a function, functionOne, defined normally, outside of other functions or if statements. Now I have another function, functionTwo, and I call functionOne inside of functionTwo. I've tried searching around but I could only find things that told me to define functionOne inside of functionTwo. My issue is that it's already defined, outside of any functions, as I said before.

Here's my code:

function functionOne (connection) {
//code here for functionOne
}

function functionTwo (functionOne, connection) {
//some code here for functionTwo

functionOne(connection)
}

The error is that the connection var isn't being passed over. Any fixes appreciated! Thanks :)

If I am understanding your question you just need to provide the argument(s) for the first function within in the second

   function funcOne(a){
    return a
}

function funcTwo(b, c){
    //funcTwo's value of "b" will be used for funcOne as the "a" argument
    return funcOne(b) + c
}

console.log(funcTwo(3,4)) //returns 7

to define a function you should use this syntax:

function funcName(args){
    //code
}

here in your example you did not define any function. you just called functions that don't exist.
