Fill in the blanks to print EVEN values from 0 to 20 using a for loop: var x = 0; for (; x <= ; x += ) { document.write(x); }

for( ; x <= 20; x += 2 ) Explanation: The loop begins with <x> being zero (an even number), it goes around while <x> is less than or equal to 20 (also an even number). The loop increments <x> by two in each iteration to be sure that the value of incremented <x> will always be an even number. Note: += operator works by adding the right hand operand (2) to the current value of the left hand operand (x).
