Write a For Loop in Javascript

To write a for loop in Javascript:

for(j=0;j<50;j++) {
document.write(j + " ");
}

Which Prints:
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49


-We created a variable and named it j because j is easy to type.
-We started j at zero. j=0
-We said as long as j is less than 50, keep going. j<50
-We incremented, or added one, each time through the loop. j++
-We used document.write to print j, plus a space, to the browser each time through the loop.
