JavaScript problem

[Random32]

Sorry if this is in the wrong section or if I'm not posting right but I need some help QUICK.

How come this is outputting "[Function]" instead of what I want the console to print? 

 

Here's the code and the website that I've been using to work on it is http://repl.it
 

var userChoice = prompt("Do you choose rock, paper or scissors?");var computerChoice = Math.random();if (computerChoice < 0.34) {  computerChoice = "rock";} else if (computerChoice <= 0.67) {  computerChoice = "paper";} else {  computerChoice = "scissors";}console.log("Computer: " + computerChoice);var compare = function (choice1, choice2) {  if (choice1 === choice2) {    return console.log("The result is a tie!");  } else if (choice1 === "paper") {    if (choice2 === "rock") {      return console.log("paper wins");    } else {      return console.log("scissors wins");    }  } else {    return console.log("paper wins");  }};var compare = function (userChoice, computerChoice) {  if (choice1 === "scissors") {    if (choice2 === "rock") {      return console.log("rock wins");    } else {      return console.log("scissors wins");    }  }};console.log(compare);

var userChoice = prompt("Do you choose rock, paper or scissors?");

var computerChoice = Math.random();

if (computerChoice < 0.34) {

  computerChoice = "rock";

} else if (computerChoice <= 0.67) {

  computerChoice = "paper";

} else {

  computerChoice = "scissors";

}

console.log("Computer: " + computerChoice);

 

var compare = function (choice1, choice2) {

  if (choice1 === choice2) {

    return console.log("The result is a tie!");

  } else if (choice1 === "paper") {

    if (choice2 === "rock") {

      return console.log("paper wins");

    } else {

      return console.log("scissors wins");

    }

  } else {

    return console.log("paper wins");

  }

};

 

var compare = function (userChoice, computerChoice) {

  if (choice1 === "scissors") {

    if (choice2 === "rock") {

      return console.log("rock wins");

    } else {

      return console.log("scissors wins");

    }

  }

};

console.log(compare);

 

 

Because you are logging a function:

console.log(compare);

Also please wrap your code in code tags

Sorry it's my first time posting here. I get what you mean by logging a function but I haven't found any solutions that make sense to me...

Right so you have this piece of code:

var compare = function (userChoice, computerChoice) {  if (choice1 === "scissors") {    if (choice2 === "rock") {      return console.log("rock wins");    } else {      return console.log("scissors wins");    }  }};console.log(compare); 

Here you are defining compare as a function.

 

Then you are using console.log to log the variable compare to the console. This will cause the function to be logged as it is stored.

You can't return a console log. When you call console.log it immediately writes the given string to the console and has no return value, so returning it will not do anything. 

 

Also, compare has parameters and in your current call to it you do not pass any to it.

Try the JavaScript course on codecademy.com, it goes over all of this and describes it really well.
