How do I make the first letter of a string uppercase in JavaScript?

Question

How do I make the first letter of a string uppercase, but not change the case of any of the other letters?

For example:

• \"this is a test\"

Answer 1

If you are wanting to reformat all-caps text, you might want to modify the other examples as such:

function capitalize (text) {
    return text.charAt(0).toUpperCase() + text.slice(1).toLowerCase();
}

This will ensure that the following text is changed:

TEST => Test
This Is A TeST => This is a test
