Help with Title Case A sentence

1

function titleCase(str) {
var newStr = “”;
var strToArray = str.split(" ");

for(var i = 0; i < strToArray.length; i++){
newStr += strToArray[i].charAt(0).toUpperCase() + strToArray[i].substr(1).toLowerCase() + " ";
}

return newStr;
}

titleCase(“I’m a little tea pot”);
titleCase(“I’m a little tea pot”);
titleCase(“sHoRt AnD sToUt”);
titleCase(“HERE IS MY HANDLE HERE IS MY SPOUT”);

This is my code^. i called the function and it returned what it was supposed to. however, only one function call seems to be working.

Hi,

It is working, but you should only call the function once at a time or you will get the result from the last call only. This is because each call overwrites newSTR.

I added a console log and they all appear in the console, this works because i’m logging inside the function, so each call generates a log.

the double at the end in " " is the return newSTR output.

function titleCase(str) {
var newStr = "";
var strToArray = str.split(" ");

for(var i = 0; i < strToArray.length; i++){
newStr += strToArray[i].charAt(0).toUpperCase() + strToArray[i].substr(1).toLowerCase() + " ";
}
console.log(newStr);
return newStr;
}

titleCase("I'm a little tea pot");
titleCase("I'm a little tea pot");
titleCase("sHoRt AnD sToUt");
titleCase("HERE IS MY HANDLE HERE IS MY SPOUT");
   I'm A Little Tea Pot 
   I'm A Little Tea Pot 
   Short And Stout 
   Here Is My Handle Here Is My Spout 
   "Here Is My Handle Here Is My Spout "

Maybe this could help:

function titleCase(str) {
var newStr = "";
var strToArray = str.split(" ");

for(var i = 0; i < strToArray.length; i++){
newStr += strToArray[i].charAt(0).toUpperCase() + strToArray[i].substr(1).toLowerCase() + " ";
}

console.log(newStr);
}
var calls = [
("I'm a little tea pot"),
("I'm a little tea pot"),
("sHoRt AnD sToUt"),
("HERE IS MY HANDLE HERE IS MY SPOUT")]

for (i = 0; i < calls.length; i++) {
    titleCase(calls[i]);
}`

i tried both of your guys’ codes and they still didn’t work. maybe theres some bug or something

Maybe it doesn’t like extra space at the end of the string? (" " - this)

6

oh yeh, theres a trailing space

this sorts it

return newStr.slice(0, -1);

Also good thing for removing unneeded spaces at the beginning and end of the string is trim function
