How can I remove the first part of the for loop?

Caleb Libby

For example, I have a variable already defined that I want to use as a counter in a for loop. I found that it is possible to replace the first expression with null, but I am wondering if it is possible to remove it completely using a different version of the for loop.

example:

function foo() {
    var i = 10;
    for(null; i > 0; i++) {
        console.log(i);
    }
}

Just don't offer anything. All 3 parts of the forloop are optional.

function foo() {
    var i = 10;
    for(; i > 0; i++) {
        console.log(i);
    }
}
