Thanks in advance!

function uppercaseFirstLetter(string) {
  return string.charAt(0).toUpperCase() + string.slice(1)

string.charAt(0).toUpperCase() takes the first letter from the given string parameter and converts it to upper case. Then, string.slice(1) adds the rest of the string on to it.

Here's how you'd use it:

uppercaseFirstLetter("tacos") // returns "Tacos"

Try this one out:

function capitalize(s) {
  return s[0].toUpperCase() + s.slice(1)
