Alexander Køpke
@alexanderkopke
@RhinoTek yes
Joshua
@jfc246
how would i do that? @alexanderkopke
Alexander Køpke
@alexanderkopke
@jfc246 what methods have you learned working with arrays? it is ok if you don't remember just asking
@jfc246 I believe you have learned about the push method and the shift method
So push pushes something to the array. Here is an example: array.push("hello"); <-- this would add "hello" to the array named array.
Joshua
@jfc246
@alexanderkopke like this?
ourArray.push(["happy", "joy"]);
Alexander Køpke
@alexanderkopke
@jfc246 exactly! Here you push ["happy", "joy"] to the ourArray array
@jfc246 in the example you're at arr is the array and item is what need to be pushed to that array
Joshua
@jfc246

@alexanderkopke so would i replace the

our Array

with

nextInLine
?
Alexander Køpke
@alexanderkopke
nextInLine is the function. You need to work inside the function and use arr as an array and itemas a variable
Joshua
@jfc246
so replace it with a
arr
Alexander Køpke
@alexanderkopke
arr.push(item); // this is the first task

I need help with the javascript escaping literal quotes in strings
NITEHAWK07
@NITEHAWK07
Can anyone help me with JavaScript Record Collection?

// Setup
var collection = {
    "2548": {
      "album": "Slippery When Wet",
      "artist": "Bon Jovi",
      "tracks": [ 
        "Let It Rock", 
        "You Give Love a Bad Name" 
      ]
    },
    "2468": {
      "album": "1999",
      "artist": "Prince",
      "tracks": [ 
        "1999", 
        "Little Red Corvette" 
      ]
    },
    "1245": {
      "artist": "Robert Palmer",
      "tracks": [ ]
    },
    "5439": {
      "album": "ABBA Gold"
    }
};
// Keep a copy of the collection for tests
var collectionCopy = JSON.parse(JSON.stringify(collection));

// Only change code below this line
function updateRecords(id, prop, value) {
  collection["5439"].artist = collection["5439"].artist.ABBA;

  return collection;
}

// Alter values below to test your code
updateRecords(5439, "artist", "ABBA");
RhinoTek
@RhinoTek
@alexanderkopke so next would be arr.shift(item);
Zane Hewgley
@zhewgley

So I am kind of confused on passing values to functions with arguments.
I am suppose to create a function called functionWithArgs that accepts two arguments and outputs their sum to the dev console. Then call the function.
// Example
function ourFunctionWithArgs(a, b){
console.log(a - b);
}
ourFunctionWithArgs(10, 5); // Output 5

// Only change code below this line.

I am confused as to where and the hell the call for (10, 5) came from. It's saying I need to create a functionWithArgs(1, 2) should output 3 and functionWithArgs(7, 9) should output 16. Then call it. I replaced the code in the example with whats given but what do I call it with...

Alexander Køpke
@alexanderkopke
\ <--this is the Houdini of escaping. Anything after you escape. \" for example @Braybray54321
Braybray54321
@Braybray54321
the instructoons are "Use backslashes to assign a string to the myStr variable so that if you were to print it to the console, you would see:
I am a "double quoted" string inside "double quotes"."
NITEHAWK07
@NITEHAWK07
Brayden is that you?
Braybray54321
@Braybray54321
@NITEHAWK07 erm what do u mean?
Joshua
@jfc246
@NITEHAWK07 @Braybray54321 do you guys know each other?
RhinoTek
@RhinoTek
@alexanderkopke like this
arr.push(item);
arr.shift(item);// Change this line
Braybray54321
@Braybray54321
@jfc246 idk
NITEHAWK07
@NITEHAWK07
I think I may know him... I have a friend at school that everyoe calls Bray Bray
Alexander Køpke
@alexanderkopke
@RhinoTek shift doesn't take an arguments. so arr.shift() is sufficient. However, you'll have to store what it removes. Like in a variable which you can then return
Braybray54321
@Braybray54321
@NITEHAWK07 Well if everyone calls that Brayden that then that's not me
NITEHAWK07
@NITEHAWK07
Do u live in the state of PA?
Alexander Køpke
@alexanderkopke
@RhinoTek var removed = arr.shift(); like this
Braybray54321
@Braybray54321
@NITEHAWK07 no
NITEHAWK07
@NITEHAWK07
ok, then not you
Braybray54321
@Braybray54321
@alexanderkopke do i put the arrows "<---" like u showed me in my string
Sam Griffen
@ssgriffen
Anyone know why my search history items when clicked are loading in the wiki articles? http://codepen.io/ssgriffen/pen/KNraGP
Braybray54321
@Braybray54321
var myStr ; // Change this line <--- this is the code it gives me
I am a "double quoted" string inside "double quotes". <---is what i need my code to of said if u were to print into console
Alexander Køpke
@alexanderkopke
@Braybray54321 no those are just for pointing.
Braybray54321
@Braybray54321
@alexanderkopke ok
Joshua
@jfc246
@alexanderkopke after several tries i can not get it to work here is my updated code
function nextInLine(arr, item) {
  // Your code here
arr.push([[], 1] );

  return item ;  // Change this line
} 

// Test Setup
var testArr = [1,2,3,4,5];

// Display Code
console.log("Before: " + JSON.stringify(testArr));
console.log(nextInLine(testArr, 6)); // Modify this line to test
console.log("After: " + JSON.stringify(testArr));

awesome!

@Braybray54321
@alexanderkopke how would i add the quotatiosn to a string of non-qutoated text
Joshua
@jfc246
@Braybray54321 do you know the answer to my question?
Alexander Køpke
@alexanderkopke
@Braybray54321 you use the escape \". So for example: "this is \"some\" string"
Diego Mayer
@Chrono79
@jfc246 why are you pushing that?
Braybray54321
@Braybray54321
@alexanderkopke ok ill see if that works
