@Zaluth soooo applying that above example to ur code.. internally its doing

function filter(value) {
    return value === join;
  }

 [1, 2, 3, 1, 2, 3].filter(filter);

return 1 === "2, 3"
return 2 === "2, 3"
etc.. on each iteration
and since that comparation return false.. it filter everything out returning a empty array

@sjames1958gm i did both those things and i am still coming up short

Stephen James

@sjames1958gm

@GodKingShogun Well only one would be needed - let me see

David Amanze

@GodKingShogun


function findLongestWord(str) {
  return str.split(" ").reduce(function(a,b) {
    return a.length > b.length ? a.length:b.length;
}).length;
}

Stephen James

@sjames1958gm

@GodKingShogun so you need to return a : b (so that previous remains a string) so that the last length makes sense

David Amanze

@GodKingShogun

@sjames1958gm so just add a return in front of the a.length part

Aaron

@aaronedwarda

whats up good people!

Stephen James

@sjames1958gm

function findLongestWord(str) {
  return str.split(" ").reduce(function(a,b) {
    return a.length > b.length ? a : b;
}).length;
}

@GodKingShogun By returning the string value the next time a.length makes sense

Ive got a question about .replace.
Can you use a variable as the parameter, such as
```var hello = "hello";

```

Ive got a question about .replace.
Can you use a variable as the parameter, such as

var me = "hello"; 
var text = "hello world";
var answer = text.replace(me);

Jason Luboff

@JLuboff

@jdc101214 Yes you can use variables with .replace

Jacob

@jdc101214

What is the proper syntax?

@JLuboff

Jason Luboff

@JLuboff

@jdc101214 There is documentation: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace

Walid Ashri

@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
