[ACCEPTED]-Reg. Expression checks first letter of a string-regex

Accepted answer
Score: 13

Your expression does not need .* nor should 3 it have the $


In fact, if you don't need 2 to know what this letter is, you could go 1 even simpler:


// These expressions are true
/^[a-zA-Z]/.test("Sample text")

var re = new RegExp('^[a-zA-Z]');
re.test('Sample text');

Try the following:


which checks if the first 2 letter is in the alphabet and allows any 1 character after that.

I was able to single out the first letter 3 with this /^[a-zA-Z].*$/ from one of the above answers, but 2 I didn't need the .\*$ so I had /^[A-J]/g (working on 1 my own assignment hence a-j).
