3. Function syntax


#1

// Below is the greeting function!
// See line 7
// We can join strings together using the plus sign (+)
// See the hint for more details about how this works.

var sayHello = function(Cameron RedGem) {
console.log("Hey" + "" + name);
};

// On line 11, call the greeting function!


I am having some trouble with this maybe someone can help out?

well they want you to use the same concept but instead of declaring sayHello, you're going to declare "greeting" and call it at the end.

so declare greeting

var greeting = function (name)
{
console.log("Nice to Meet you" + " " + name); <----this will print out "Nice to Meet you" with what you plan to put as the name
};
greeting("what ever name you want to fill here");

should be able to work. i hope :blush:

@cameronredgem,
You will have to change your argument into a string Value "Cameron RedGem"

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".**

I don't see how this side of the code will work since the system has a some code when started.

Code when started
// Below is the greeting function!
// See line 7
// We can join strings together using the plus sign (+)
// See the hint for more details about how this works.

var greeting = function (name) {
console.log("Great to see you," + " " + name);
};

// On line 11, call the greeting function!

doesn't work out that good for me. :disappointed:


#6

it works, just copy paste :smile:

var greeting = function (name)
{
console.log("Nice to Meet you" + " " + "Vesela");
};
greeting("what ever name you want to fill here");
