function capitalizeSentences(text) {
return text.replace(/(^\w|\.\s*\w)/g, function(match) {
return match.toUpperCase();
});
}
var text = "this is how you would captilize this sentence. this is another sentence"
var capitalizedText = capitalizeSentences(text);
console.log(capitalizedText)
// >>> This is how you would captilize this sentence. This is another sentence
The replace method is used with a regular expression pattern to match the first word character after the start of the string (^\w) or after a period followed by zero or more whitespace characters (\.\s*\w).
