@Kelvin-penang

Hi all, I'm trying to split each word of a string into seperate arrays of alphabets, within a larger array of the whole string. What I'm looking for is this ["I","'","m"] ["a"]["l","i","t","t","l","e"]...you get the point,

but I'm stumped on how to split the words, can anybody help?

```


function titleCase(str) {
  var splitOnce = str.split(" ");

 for (var i=0; i <splitOnce.length; i++){
  var splitTwice = splitOnce[[i][i]].split("");

  return splitTwice;
}
}
titleCase("I'm a little tea pot");

@Myuuks That's not code, it's a screenshot.

@Myuuks

yeah how can i do ?

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

"when i saw a " + myAdjective + myNoun + "i " + myVerb + myAdverb;

// Your code above this line
return result;
}

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

@Myuuks

looks wierd like this on my screen

Blauelf

@Blauelf

@Myuuks You should probably use result = in front of your string. Also, the words are not all separate.

@Blauelf

@Kelvin-penang You can type ``` without it being interpreted by using \ as an escape character.

@Myuuks Please put a line of triple backticks in front of your code, and one below, add line breaks using Shift+Return.

@parihars contacts is an array. Make a standard for loop over array indices.

@zhangx007

hello,i am new here

Markus Kiili

@Masd925

@parihars It is contacts.

Saurabh Parihar

@parihars

@Masd925 yeah i m changing it

Markus Kiili

@Masd925

@parihars Then figure out how to access one contact inside the array of contacts.

Blauelf

@Blauelf

@Myuuks
```js
function yourCode(arg1) {
var foo;
return "bar";
}
```
becomes

function yourCode(arg1) {
  var foo;
  return "bar";
}

@Myuuks

allright thanks

sorry, wandered off for a bit

Myuuks

@Myuuks

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

 result = "when i saw a " + myAdjective  + myNoun + "i " + myVerb + myAdverb;

  // Your code above this line
  return result;
}

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

it works but

Keone Martin

@Athaman

remember myuuks if you take "one word" + "another word" you get "one wordanother word" so when you add two words together which are stored as variables, like myAdjective and myNoun, you need to use myAdjective + " " + myNoun

// Change the inputs below to test
rot13("SERR PBQR PNZC");

what is the problem?
TypeError: Cannot assign to read only property '0' of string 'SERR PBQR PNZC'

there is also else condition

@parihars : Sorry I don't know the problem statement. I just fixed syntax and semantic errors.

@Myuuks

is that better @Athaman :

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

 result = "when i saw a " + myAdjective+ "" + myNoun + "i " + myVerb + "" + myAdverb;

  // Your code above this line
  return result;
}

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