Question

I have a string like “word_count”. How can I transform it to “WordCount” in an elegant way using JavaScript? My decision seems too complicated to me. I’ll be very grateful for your help.

Answer 1

function titleCase(str)
{
    return str.split("_")
        .map(function (s) { return s.charAt(0).toUpperCase() + s.slice(1); })
        .join("");
}
