Capitalizing first letter of each word in a string

JavaScript

Tell us what’s happening:
I apologize for my frequent questions, but I don’t understand why the code fails to return the correct result when dealing with the “I’m a little tea pot” string

Your code so far


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

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

Here is what you code return for the str = “I’m a little tea pot”

//I’M A Little Tea Pot

You should find a way to handle that “M”

I solved the problem by doing function titleCase(str) { return str.toLowerCase().replace(/\b(\w)/g, r => r.toUpperCase()).replace(/'m/i, m => m.toLowerCase()); }But that will only work for that specific example, are there any better ways of dealing with it?

Positive lookaheads perhaps?

5

How would that work? Examples?

Not much I can do without giving the answer unfortunately.

But you can mess with regex in this site:

Comes with explanations of what regex you used!
