Check if first letter of word is a capital letter

Question

Is it possible in Javascript to find out if the first letter of a word is a capital letter?

Answer 1

Typescript

//userEntry input as string
//return boolean
oneUppercaseRequired(userEntry: string): boolean {
   const letters = /[A-Z]/;

   if (letters.test(userEntry[0]))
     return true;

   return false;
}

for-loop for other languages Change the syntax to your language!

//userEntry param as string
//return boolean
oneUppercaseRequired(userEntry: string): boolean {
   const letters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";

   for (let i = 0; i < letters.length; i++) {
     if (userEntry[0] == letters[i])
       return true;
   }

   return false;
}
