Utilize
function convertFirstLetterToUppercase(sentence: string) {
return sentence.replace(/(?<![\w'])\w/g, char => char.toUpperCase());
}

(?<! searching for absence of:
--------------------------------------------------------------------------------
[\w'] any characters from: alphanumeric characters (a-z,
A-Z, 0-9, _), '''

\w alphanumeric characters (a-z, A-Z, 0-9, _)
Keep in mind the g flag is used to replace all occurrences, not s.
If you want to capitalize all words in a string, you can utilize the callback function of the replace method.
function capitalizeAllWords(str: string) {
return str.replace(/'[a-z]|\b([a-z])/g, (m, g1) => g1 ? g1.toUpperCase() : m);
}
In this regex pattern, you capture the letters you want to uppercase in group 1 and match the rest to be left untouched.
'[a-z]|\b([a-z])
Here's a breakdown:
'[a-z] will match any occurrence of ' followed by a lowercase letter| Or\b([a-z]) uses word boundaries to avoid partial matches and captures a lowercase letter in group 1To see how this works, check out the Regex demo.
const regex = /'[a-z]|\b([a-z])/g;
const str = "Men's apparel $test";
let res = str.replace(regex, (m, g1) => g1 ? g1.toUpperCase() : m);
