The following code throws an error in the browser console

sayHello(firstName, lastName){
 
let msg = "Greetings ";
 
function intro(){
 
return
 
msg + firstName = " " + lastName;
 
}
 return into();
}
sayHello("Professor" , "Falken");
 
//returns "Greetings Professor Falken";

After the comment lines is what should come out. However an error is declared, indicating that the first key is an unexpected token. I need an explanation to correct the code.

I have the following 3 functions that I would like to call in a single function in kotlin: to write a single number and that I evaluated all 3, I leave my codes. I mean, create a 4th function that calls the other 3, for example, the fun function called AtodasLasFunciones helps me to call the others, how would the parameters be given, thanks, I'm new to Kotlin

fun llamadaAtodasLasFunciones(no se como llamarlas :( ) { 
}
 

fun meses2021(mesesCorrientes : Int) {
    when(mesesCorrientes){
    1 -> println("Enero")
    2 -> println("Febrero")
    3 -> println("Marzo")
    4 -> println("Abril")
    5-> println("Mayo")
    6 -> println("Junio")
    7 -> println("Julio")
    8-> println("Agosto")
    9-> println("Septiembre")
    10 -> println("Octubre")
    11 -> println("Noviembre")
    12 -> println("Diciembre")
    else -> { 
    println("No esta dentro de los meses del año")
    
}
}
}

fun apuntarMese(apuntar : Int) {
    when(apuntar) {
    1,2,3,4 -> println("corresponde al primer cuatrimestre")  
    5,6,7,8 -> println("corresponde al segundo cuatrimestre")
    9,10,11,12 -> println("corresponde al tercer cuatrimestre")
    else -> { println("No esta dentro de los meses del año")
    }
}
}

fun mesesRango(mes: Int) {
when(mes) {
    in 1..6 ->println("Primer semestres del año")
    in 7..12 ->println("Segundo  semestres del año") 
    !in 1..12 ->println("No corresponde a los meses que necesita") 
    }
}

I'm reading the kotlin tutorial in codelads and this question came up, because in the codelabs they show us examples but not one of this type, so what I want is something like this:

var dirtyLevel = 20
val waterFilter: (Int) -> Int = { dirty -> dirty / 2}// funcion lambda
val updateDirty: Int = { dirty : Int, operation : (Int) -> Int -> operation(dirty)}// funcion lambda de orden superior
println(waterFilter(dirtyLevel))
println(updateDirty(30,waterFilter))

generates this error:

error: type mismatch: inferred type is (Int, (Int) -> Int) -> Int but Int was expected
val updateDirty: Int = { dirty : Int, operation : (Int) -> Int -> operation(dirty)}
                       ^

I also tried it like val updateDirty: Int = { (dirty : Int, operation : (Int) -> Int) -> operation(dirty)}this but it generates this error:

error: type mismatch: inferred type is (???) -> [ERROR : <ERROR FUNCTION RETURN TYPE>] but Int was expected
val updateDirty: Int = { (dirty : Int, operation : (Int) -> Int) -> operation(dirty)}

In other languages ​​when you work with a function, it is written...

public void funcion_ejemplo(int variable1, int variable2){
  // la función trabaja con las vaiables que reciba
}

So when I want to use this function I would call it and send it data, like this:

funcion_ejemplo(12,5);

In this way I send variables to this function so that it is executed with different variables.

Now at GameMaker we have the Scripts, which we call:

Create_bomba();

enter image description here

. Is there a way to send variables to this script? . In case you don't find a way, I was thinking of creating global variables, and that the scripts use these global variables

I am relatively new to TypeScript and am reviewing both documentación oficialthe GitHub.

In one of these GitHub examples there is a function urithat passes arguments without using parentheses ( ejemplo completo):

public async getRateLimit() {
    return this.get<RateLimit>(uri`/rate_limit`);
}

Here is the implementation of this function:

function uri(template: TemplateStringsArray, ...args: any[]): string;
function uri(template: TemplateStringsArray) {
    let text = template[0];
    for (let i = 1; i < template.length; i++) {
        text += encodeURIComponent(String(arguments[i]));
        text += template[i];
    }
    return text;
}

I can't see this way of calling functions documented anywhere. I would really appreciate a link to the documentation or an explanation if I'm wrong.
