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

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(" ");
}

@sunstevensun

has anyone done "No Repeats Please"?

Tejanth

@Tejanth

@camperbot

:warning: could not find receiver for suyang581

silver537

@silver537

@Tejanth its just the logic FCC is looking for.

CamperBot

@camperbot

tejanth sends brownie points to @suyang581 :sparkles: :thumbsup: :sparkles:

Su Yang

@ssxyang

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

@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)

bkapadia

@bkapadia

min and max values are correct just the for loop isn't output the total

Diego Mayer

@Chrono79

@bkapadia i==max isn't a good condition for your loop

manugp

@manugp

@Chrono79 did it

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

bkapadia

@bkapadia

hmm

Diego Mayer

@Chrono79

@manugp not very orthodox, but congrats :+1:

silver537

@silver537

A bit too much. Actually. But hey, if it works, it works. :P

bkapadia

@bkapadia

i<=max

Diego Mayer

@Chrono79

@bkapadia :+1:

silver537

@silver537

@manugp do you understand what your code is doing?

Braybray54321

@Braybray54321

function myLocalScope() {
'use strict';

console.log(myVar);
}
myLocalScope();

// Run and check the console
// myVar is not defined outside of myLocalScope
console.log(myVar);

// Now remove the console log line to pass the test

It says to delcrare local variable myVar inside mylocalscope
than follow the instructions please help
