Doing the short capitalization challenge, pretty sure I have the right results but it says I dont.

  **Your code so far**


function titleCase(str) {
let str2 = []
str2 = str.split(' ');
str = ''
for(let i = 0; i < str2.length; i++){
  str += (str2[i].substr(0,1).toUpperCase()).concat(str2[i].substr(1).toLowerCase() + ' ');
  //console.log(str)
}
str.trim();
//console.log(str)
return str;
}

//titleCase("I'm a little tea pot");
console.log(titleCase("sHoRt AnD sToUt"));
console.log(titleCase("HERE IS MY HANDLE HERE IS MY SPOUT"))

this doesn’t mutate the string

I’ve been recently advised to make more use of new variables when making assignment (=) so to use ‘const’ more than ‘let’.
(i’m just a noob, so pinch of salt with my advice, but i think you could apply that here). some functions mutate a value (could be best avoided anyway) and some return a new thingumeejig. )

I see, I didnt realize that. I just set the return value to str.trim() and it worked, thx for the heads up.

5

ok.
const str2=str.trim() wud also work

6

I wouldn’t overwrite the input like this.

Why not use

const str2 = str.split(' ');

This really isn’t a great variable name.

I’d format it more like this for readability:

str += str2[i][0]
  .toUpperCase()
  .concat(str2[i].substr(1).toLowerCase()) + ' ';
