Word Blanks Exercise

Tell us what’s happening:

I don’t understand why this is right! I caved in and hit the “Get a hint” button to get the missing information. My original code was way off.

Not sure how I was able to pass the 3 required items below with this line of code. result+= “My “+myAdjective+” “+myNoun+” “+myVerb+” very “+myAdverb+”.”;

Passed

wordBlanks("","","","") should return a string.

Passed

wordBlanks("dog", "big", "ran", "quickly") should contain all of the passed in words separated by non-word characters (and any additional words in your madlib).

Passed

wordBlanks("cat", "little", "hit", "slowly") should contain all of the passed in words separated by non-word characters (and any additional words in your madlib).

Your code so far
var


function wordBlanks(myNoun, myAdjective, myVerb, myAdverb) {
  // Your code below this line
  var result = "";
result+= "My "+myAdjective+" "+myNoun+" "+myVerb+" very "+myAdverb+".";
  // Your code above this line
  return result;
}

// Change the words here to test your function
wordBlanks("dog", "big", "ran", "quickly");

If you add console.log(result) as last line before the “your code above this line”, you will see printed in the console the string

You will see that you have created a string with the arguments of the function (last line of the whole code) in the place of the variables. You can change those arguments and you will see the text in the console change

But right now you just need to understand how to concatenate strings contained in variables with other strings , the function part will be explained later

Hi ieahleen,

I see that I get “My big dog ran very quickly.”

I even played around with the code. I was able to add to it.

I understand concatenation. What I don’t understand is how it knows where out pull the word list from based on the code. I’m going to keep playing with it till I get it.


function wordBlanks(myNoun, myAdjective, myVerb, myAdverb, newword) {
  // Your code below this line
  var result = "";
result+= "My "+myAdjective+" "+myNoun+" "+myVerb+" very "+myAdverb+" "+newword+".";
  // Your code above this line
  return result;

  console.log(result)
}

// Change the words here to test your function
wordBlanks("dog", "big", "ran", "quickly", "outside");

This is a function call (last line of the code), the values in the parenthesis are the values that are passed in the function

This is the function declaration, the variables in the parenthesis are the parameters - when a function is called the code is executed passing the arguments in the function parameters

Functions is a future subject, you will find it in a few lessons and understand what happens here better

This is the command to print things to the console, though you should put it before the return statement if you want it to be executed

This is the return statement, and in this way you declare what value should be returned from the function

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.
