The code will print 'Hello' once. The for(;;) syntax creates an infinite loop in JavaScript, as it omits all three components of the for loop (initialization, condition, and update) which effectively means 'loop forever'. However, the break statement inside the loop immediately terminates it after the first iteration, so 'Hello' is only printed once. This is a valid (though unusual) pattern in JavaScript: creating an infinite loop and then using conditional break statements to exit when needed, though it's generally clearer to express the loop condition explicitly.
