@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

@Athaman

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

Caesars cipher

function rot13(str) { // LBH QVQ VG!
  for(var i=0;i<str.length;i++) {
    if(str.charCodeAt(i) >= 65 && str.charCodeAt(i) <= 90) {
      if(str.charCodeAt(i) < 78) {
        str[i] = String.fromCharCode(str.charCodeAt(i) + 13);

      }
    }
  }
  return str;
}

// 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'

Saurabh Parihar

@parihars

there is also else condition

@adityaparab

Darth Skywalker

@adityaparab

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

Myuuks

@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");

@Athaman

"" is no space " " is a space

Myuuks

@Myuuks

ok :)

Keone Martin

@Athaman

also you'll need a space in front of i so " i "

this challenge is just to make people aware of how annoying joining strings can be :D

Thanks @Athaman :)

Call the processArg function with an argument of 7 and assign its return value to the variable processed.

// Example
var changed = 0;

function change(num) {
  return (num + 5) / 3;
}

changed = change(10);

// Setup
var processed = 0;

function processArg(num) {
  return (num + 3) / 5;
}

// Only change code below this line


processArg(7);
return processed;
