Because the first letter of the string on the left, the A in apple,
comes before the first letter of the second string

Because the first letter of the string on the left, the A in apple,
comes before the first letter of the second string, the B in bear.
That is A comes before B in the alphabet.

1- I don’t understand how A<B is ‘true’. A is before B.. isn’t it A>B? 2- “That is if you compared a number and a letter, a number is less than a letter.” Meaning, 1 < A?

Jasmin chang , Good question. Think of it this way, if you were to arrange A-Z sequentially, you would have:

1. A
2. B
3. C
...
26. Z

This way, A = 1 and B = 2 hence, 

A < B // 1 is less than 2 :)

I believe it's because of the charcodes:

console.log(String.fromCharCode(65));   // A
console.log(String.fromCharCode(66));   // B
console.log(String.fromCharCode(97));   // a
console.log(String.fromCharCode(98));   // b

console.log(String.fromCharCode(49));   // 1
console.log(String.fromCharCode(57));   // 9

thanks, guys, so 'before' means.. smaller? I guess 'before' meaning is what's tricking me here.
