Just finished the for loop video and example code. So basically a for loop is like a while and a do while loop?

These for loops are pretty sweet and easy to understand. I struggle with loops all the time and this for loop actually made sense. In the video Dave stated that for loops are like while and do while loops, is that a correct statement? Can I do what while, and do while loops do with a for loop, or are there somethings only while and do while loops can do?

Thanks in advance for any input/feedback....AND I LOVE FOR LOOPS :D

do while loops always execute a statement once before entering the loop. Unlike while and for loops, the statement inside their code block depends on the evaluation of the expression in the loop.

do {
     // this will execute at least once regardless of the result of the condition in the while
     alert("People who can't do something themselves will tell u u can't do it.");
} while (1 > 10);



while (1 > 10) {
    // BAM! this never happened, the condition is false.
       alert("People who can't do something themselves will tell u u can't do it.");
}
