paste your code and mention your problem

@lubere0102

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

@lubere0102 so the challenge gives you a function call with a bunch of words called myNoun, myAdjective, myVerb, myAdverb.

how to solve Profile Lookup problem

Keone Martin

@Athaman

you need to stick them together into 1 string called result

@lubere0102

Keone Martin

@Athaman

you can join strings together using the + operator

@lubere0102

Keone Martin

@Athaman

var oneWord = "whargarbl";
var anotherWord = "blargh";
var together = oneWord + anotherWord // together now = "whargarblblargh" <-- notice that no space was added between the words

@lubere0102

how do you capture like that?

@Athaman

@parihars which part is confusing you?

Subh Samal

@subhsamal

var result = "my " + myAdjective +" "+ myNoun +" " + myVerb+" " + myAdverb; @lubere0102 try like this

Keone Martin

@Athaman

bro, if you give people the answer directly like that it doesn't really give them a chance to learn the content

also in the challenge var result = ""; has already been set... so you just want result = ... :P

Subh Samal

@subhsamal

my bad :P

@lubere0102

thank you i just didn't get what i was supposed to do

Keone Martin

@Athaman

no problem :) sorry if i sounded hostile, i'm struggling to find the right words but it's a common thing on the channel to just give the answers which i think isn't the best solution

sometimes if someones obviously got the logic and just has a typoe, or uses the wrong variable somewhere or something it makes sense to just tell them where it's wrong and pass the solution, but normally i start off with clues and analogies.

Subh Samal

@subhsamal

yes you sound correct buddy

thank you all

@Athaman

no problem @lubere0102 :) enjoy the challenges

@lubere0102

thank you for that capturing method too


function wordBlanks(myNoun, myAdjective, myVerb, myAdverb) {
  var result = "";
  // Your code below this line

    var result = "my " + myAdjective +" "+ myNoun +" " + myVerb+" " + myAdverb; 
  // Your code above this line
  return result;
}

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

Keone Martin

@Athaman

no worries, it's good to know. much easier to help people when the code is all pretty and formatted

@lubere0102

very good

Michael

@michaelpautov

hello
var myVar = 87;

// Only change code below this line
myVar = myVar;
myVar = myVar;
myVar = ++myVar;

dont' working ex myVar = myVar should be changed

Keone Martin

@Athaman

myVar = myVar; won't do anything, all it does is tell myVar to be itself

like 5 = 5;

the increment by one shorthand needs to be on the end of the variable like myVar++;

but it doesn't need to be reassigned because that's part of the short hand

so myVar = myVar++; is the same as myVar = myVar = MyVar + 1;

Blauelf

@Blauelf

++myVar first increments myVar, then evaluates to the incremented value (in contrast to myVar++, which also increments myVar, but evaluates to the old value), so myVar = ++myVar; should be same as ++myVar;

Keone Martin

@Athaman

oh right, i didn't think JS had increment first in it sorry...

Michael

@michaelpautov

thank

Keone Martin

@Athaman

you're welcome

Myuuks

@Myuuks

@Athaman i dont understand what's asked for the exercice called "Woord Blanks"

-o

Blauelf

@Blauelf

You are meant to return a sentence containing all those words passed to your function.

Keone Martin

@Athaman

similar to before when you used your name + another string

Blauelf

@Blauelf

@Myuuks So for "big","dog","ran","quickly" it might return something like "When I saw a big dog, I ran quickly."

diff btwn two arrays .there is a mistake in if loop but i dnt know to recify it


function diffArray(arr1, arr2) {
  var newArr = [];
  var oldArr=[];
  // Same, same; but different.
  for(var i=0;i<arr1.length;i++)
    {
      for(var j=0;j<arr2.length;j++)
      {  
      if(arr1[i]==arr2[j])

      newArr.push(arr2[j]);
        else
          oldArr.push(arr2[j]);

      }

    }

  return newArr;
}

diffArray([1, 2, 3, 5], [1, 2, 3, 4, 5]);
