This behaviour is called Coercion.
If you compare a string to a number the, string will be converted to a boolean (true if the string is not empty, false otherwise) and that boolean again is converted to a number (1 if the boolean is true, 0 otherwise).
In the case of your code the string "ghh" is converted to "true" and inturn converted to
"1" which becames:
if (8 > 1) {
// Will execute because the condition is true.
} else {
// Will not execute because the condition is not false.
}
