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

var word = "Someword";
console.log( word[0] === word[0].toUpperCase() );

or

var word = "Someword";
console.log( /[A-Z]/.test( word[0]) );

or

var word = "Someword";
console.log( /^[A-Z]/.test( word) );

See toUpperCase() and test()
