@GodKingShogun

i said /D earlier because /d targets digits and the opposite of any regexp is capitalized

Diego Mayer

@Chrono79

@GodKingShogun let's go with this path:

@GodKingShogun you could use split(" "), to get an array of words, change each word, and then use join(" ") to get a string back

var count = 0;

function cc(card) {
// Only change code below this line
switch(card){
case 2:
case 3:
case 4:
case 5:
case 6:
count ++;

  break;
case 7:
case 8:
case 9:
  break;
case 10:
case "J":
case "Q":
case "K":
case "A":
  count --;
  break;

}

if (count<1) { return count+" Hold"; } else if (count>1){
return count+" Bet";
}
// Only change code above this line
}

// Add/remove calls to test your function.
// Note: Only the last will display
cc(2); cc(2); cc(10);

@Chrono79

@chocochip15 what if count is 1?

David Amanze

@GodKingShogun

@Chrono79 what would i use for the change each word part

Anshul Bisht

@chocochip15

thnx man ;)

Diego Mayer

@Chrono79

@GodKingShogun word[0].toUpperCase() + the rest of the word

Anshul Bisht

@chocochip15

@Chrono79 thnx man

function titleCase(str) {
  return str.split(" ")[0].toUpperCase().join(" ");
}

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

this is what i have so far

Diego Mayer

@Chrono79

@GodKingShogun you should use some kind of loop, a real loop, or if you want to chain methods, use map
With that code, you get "I'M"

David Amanze

@GodKingShogun

@Chrono79 ok let me try using the map method

@anweshd

how to change myVar=myVar??

silver537

@silver537

@GodKingShogun dont forget to add the rest of the word to your str.split (" ")[0]

Tejanth

@Tejanth

hello everyone

I have this code but I need some help

var a = 7;
var b = 7;

it says a should be assigned to b with =

how would I do that?

Su Yang

@ssxyang

@Tejanth var b = a;

Tejanth

@Tejanth

why doesnt var a=b work?

Su Yang

@ssxyang

@Tejanth the question asks for var a to be assigned to var b

Tejanth

@Tejanth

oh ok

Su Yang

@ssxyang

var a = b would work if you first defined var b = 7 and the question asked for var b to be assigned to a

David Amanze

@GodKingShogun

@Chrono79 and @silver537 ```

Tejanth

@Tejanth

yes i think that just takes some getting used to

just started this language

David Amanze

@GodKingShogun

function titleCase(str) {
  return str.split(" ").map(function(val) {
   return val.toUpperCase();
}).join(" ");
}

Steven Sun

@sunstevensun

has anyone done "No Repeats Please"?

Tejanth

@Tejanth

thank @suyang581

@silver537

@Tejanth its just the logic FCC is looking for.

Su Yang

@ssxyang

@Tejanth yep! you'll get used to it (:

Alexander Køpke

@alexanderkopke

@Zaluth you have seek.indexOf(slice) === -1; but slice if I understand correctly is an array. I think this would be ok if there was an array in seek but there are only items of numbers. Use indexOf on slice to find out if value is present in slice or not. I think this should happen in the filter function that you made since it is that function that returns the array you'll return in the end.

Diego Mayer

@Chrono79

@GodKingShogun now you're uppercasing the whole word, first, lowercase the whole string (before using split) and then rebuild your word as the first letter uppercased and the rest of the word
Have you heard of string concatenation?

silver537

@silver537

@GodKingShogun no. That will output EVERYTHING in uppercase.

David Amanze

@GodKingShogun

@Chrono79 i tried adding bracket notation to the val but i t only return the first letter in each word

Diego Mayer

@Chrono79

@GodKingShogun remember I told you to use slice

bkapadia

@bkapadia

function sumAll(arr) {
var add =0;
var min=Math.min(...arr);

var max=Math.max(...arr);

for(i=min;i==max;i++){
add=add+min;
}
return add;
}
sumAll([1, 4]);

silver537

@silver537

@GodKingShogun remember in the previous challenge you had used a string method called splice. Which basically cuts a string where you specify. So '"hello".splice (1)=>ello` because youre cutting the string at the first letter.

David Amanze

@GodKingShogun

@Chrono79 thats where you add a +

bkapadia

@bkapadia

any idea why this code gives value of 0

David Amanze

@GodKingShogun

@Chrono79 i tried adding bracket notation to the val but i t only return the first letter in each word

silver537

@silver537

Slice* sorry. On my phone and cant edit my messages. :(

Diego Mayer

@Chrono79

@GodKingShogun look at the example @silver537 gave you (and yes, it's slice, splice is an array method)
