How can i capitalize first letter of Each Word in javascript, reactjs

Question

I want to capitalize every first letter of Each Word in reactjs

Only Letter of Word capitalize but I want to capitalize every first letter of Each Word

const handleCapitalClick = () => {
    console.log("Capitalize first Word " + text);
    var firstChar = text.slice(0, 1).toUpperCase();
    var restOfWords = text.slice(1, text.length);
    const Newtext = firstChar + restOfWords;
    setText(Newtext);

    // .split(' ') 
};

And I know .split(' ') I use for words.
