@walidashri

@jdc101214 you still need 2nd arg in replace

Jacob

@jdc101214

@walidashri That wasnt a literal example

David Amanze

@GodKingShogun

i am working on a challenge and i am trying to think of how to apply the code to solve the problem. is it possible to call .split() two times in a row

Walid Ashri

@walidashri

ok sorry but this gonna work :+1:

Jason Luboff

@JLuboff

@GodKingShogun What do you mean by call split twice?

Jacob

@jdc101214

@JLuboff Where does it talk about the variables?

RhinoTek

@RhinoTek

I am stuck on 'Stand In Line' with no idea where to start. Anyone get there yet?

Jason Luboff

@JLuboff

@jdc101214 Did you look through it? There's examples throughout the page..

David Amanze

@GodKingShogun

@JLuboff can i go str.split(" ").split(" ") or is that bonkers

Jacob

@jdc101214

is there?

Stephen James

@sjames1958gm

@GodKingShogun bonkers

Jason Luboff

@JLuboff

@GodKingShogun The second split wouldn't do anything

Stephen James

@sjames1958gm

split returns an array which doesnt have split

Jason Luboff

@JLuboff

@jdc101214 Yes, there is literally a section called "Examples"

David Amanze

@GodKingShogun

@JLuboff ok. ill be back soon. i have to go smash 10 eggs on my head for my foolishness

lol

Jason Luboff

@JLuboff

I'll be long gone into the weekend..

:laughing:

Jacob

@jdc101214

@JLuboff I just word searched the page and couldn't find the word "variable" in the whole page...

Jason Luboff

@JLuboff

@jdc101214 Look at the examples. They use variables in the examples

Jacob

@jdc101214

ok I see it now. Thanks @JLuboff

@JLuboff

Have a good weekend all

David Amanze

@GodKingShogun

@JLuboff i am on the title case problem and it wants me to capitalize the first letter in each word in a string. Basically i will have to use the .split,.map, and .join method to complete this challenge right

Jacob

@jdc101214

Why is this code not working?

function destroyer(arr) {
  // Remove all the values
  var arr1 = "";
  for(var i = 0; i < arguments.length; i++){
    arr1 = arguments[0[i]].replace(arguments[i], "");
  }

}

destroyer([1, 2, 3, 1, 2, 3], 2, 3);

David Amanze

@GodKingShogun

@JLuboff have a good weekend after you answer my last question lol

HeebieGeeBee

@HeebieGeeBee

what are arguments?

in this code

Alexander Køpke

@alexanderkopke

arguments are what you pass to a function

HeebieGeeBee

@HeebieGeeBee

i mean in his code

what do his parameters 'arguments' mean

Walid Ashri

@walidashri

@jdc101214 I think replace is a String method

Jacob

@jdc101214

your right....

Why doesnt it work with everything!!!!!!!

Alexander Køpke

@alexanderkopke

@HeebieGeeBee destroyer is the function and it has arr as a parameter... when you call it you can pass arguments like this: destroyer([1, 2, 3, 1, 2, 3], 2, 3); the arr parameter will be [1, 2, 3, 1, 2, 3]

Walid Ashri

@walidashri

@HeebieGeeBee all what is passed between the () when you call the function

HeebieGeeBee

@HeebieGeeBee

so i can just write arguments into code?

instead of arr or whatever the actual argument is called

so in this code would arguments.length do the same things as writing arr.length?

Alexander Køpke

@alexanderkopke

@HeebieGeeBee yes arguments will hold whatever is being passed. It is array like but not an actual array, So if you treat it like a normal array it might cause problems

there are three arguments passed. arr will take the first arguments which is the array

HeebieGeeBee

@HeebieGeeBee

oh ok cool ty @alexanderkopke and @walidashri

@alexanderkopke

to access the other arguments you can use arguments

@jfc246

how do i assign lots of different objects to return different things? i'm stuck on Stand in Line
i think that is the problem
code:


function nextInLine(arr, item) {
  // Your code here

  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));
