Help a brother out!

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”.

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 ) );
