Trying to do my own loop ... can not find the problem


#1

var choice1 = prompt("Choose a bank");
var choice2 = loanSelection

console.log(choice1)

var list = ["PN", "ANZ", "NAB", "WBC", "CBA", "BWEST"];
console.log(list)
var loanSelection = function(list){   
    for(var i = 0; i <= list.length; i++){
    if(choice1 === list){
    return(list[i]);
}
else{
    console.log("Incorrect input")
    }}};
console.log(loanSelection())

var match = function(choice1, choice2){
if (choice1 === choice2) { 
    return(rates())
}
if(loanSelection() === "PN") {
    return(list[0] + " Has a rate of 4.15%");
}
if(loanSelection() === "ANZ"){
    return(list[1] + " Has a rate of 4.13%");
}
if(loanSelection() === "NAB"){
    return(list[2] + " Has a rate of 3.98%");
}
if(loanSelection() === "WBC"){
    return(list[3] + " Has a rate of 4.02%");
}
if(loanSelection() === "CBA"){
    return(list[4] + " Has a rate of 3.9%");
}
if(loanSelection() === "BWEST"){
    return(list[5] + " Has a rate of 3.99%");
 } else {
    return("Check your spelling."); 
    }};
console.log(match())

@textjumper38976,
Read the Function talk
in mean time you could use

var list = ["PN", "ANZ", "NAB", "WBC", "CBA", "BWEST"];
console.log(list);
var loanSelection = function(aList){   
    for(var i = 0; i < aList.length; i++){
      if(choice1 === aList[i]){
        return aList[i];
      }
    }
    return "Incorrect input";
};


var match = function(aChoice1, aChoice2){
    //test if choice1 made is a valid bank
    if (aChoice1 === aChoice2) { 
        return rates(aChoice1);
    }
    else {
        return aChoice1 +" is a unknown/not-registered Bank !!";
    }
};
var rates = function(aChoice1) {
if(aChoice1 === "PN") {
    return(list[0] + " Has a rate of 4.15%");
}
if(aChoice1 === "ANZ"){
    return(list[1] + " Has a rate of 4.13%");
}
if( aChoice1 === "NAB"){
    return(list[2] + " Has a rate of 3.98%");
}
if(aChoice1 === "WBC"){
    return(list[3] + " Has a rate of 4.02%");
}
if(aChoice1 === "CBA"){
    return(list[4] + " Has a rate of 3.9%");
}
if(aChoice1 === "BWEST"){
    return(list[5] + " Has a rate of 3.99%");
 } else {
    return("Check your spelling."); 
 }
};


var choice1 = prompt("Choose a bank","BWEST");
var choice2 = loanSelection(list);

console.log("choice1: "+choice1);
console.log("choice2: "+choice2);
console.log(match(choice1,choice2));

=========================================================

### the FUNCTION talk

var myFunc = function( param1, param2) {
       //Begin of  anonymous FUNCTION-BODY
       //VARIABLE -myFunc- has an -anonymous function- assigned
       //this -anonymous function- has 2 PARAMETERS param1 and param2
       //param1 and param2 PARAMETERS are used 
       //as -local- VARIABLES throughout the FUNCTION-BODY

      console.log( param1 + " and " + param2 ) ;

      //End of anonymous FUNCTION-BODY
};

If you want to call/execute the anonymous function
you will have to add a pair of parentheses to the variable myFunc
like
myFunc();
As the anonymous function was defined
as having 2 parameters
you have to provide 2 arguments
in our case 2 string VALUES "Alena" and "Lauren"
like
myFunc("Alena","Lauren");

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

function with 1 parameter using return-statement

var myFunction = function( param1 ) {
       //Begin of FUNCTION-BODY
       //myFunction =function= has 1 PARAMETER param1
       //this param1 PARAMETER is used as a -local- VARIABLE
       //throughout the FUNCTION-BODY

      return param1;

      //End of FUNCTION-BODY
      };

you have defined a myFunction function
which takes 1 parameter param1
this param1 parameter is used
as a variable throughout the FUNCTION-BODY.

If you want to call/execute this myFunction function
and this myFunction function was defined
as having 1 parameter param1
you will have to provide 1 argument
in our case a "number VALUE" 4
myFunction( 4 );

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

============================================

As you are using the return-statement in your myFunction function
you will only get a return-value no-display.
You can however capture this return-value in a variable
and then use the console.log()-method to do a display.

var theResult = myFunction( 4 );
console.log( theResult );

OR directly

console.log( myFunction( 4 ) );
