Hey, can anyone tell me what am I doing wrong in Title Case a Sentence challenge?

[nimerria19]

Here’s my code it works just fine, but if we pass it a string “I’m a little tea pot”, it returns “I’M A Little Tea Pot”, not “I’m A Little Tea Pot”.
I’d appreciate if anyone could help me

function titleCase(str) {
    let lowerStr = str.toLowerCase();
    let newStr = lowerStr.replace(/\b\w/g, c => c.toUpperCase());
    return newStr;
}

I think the \b token does not do what you want it to do. It looks for chars that do not match \w, which would include the apostrophe.
