how could I reduce the cyclomatic complexity?

Question

Whenever I lint a piece of code I\'m working on I get the This function\'s cyclomatic complexity is too high. (7). But I\'m a bit confused on how I could rewrit

Answer 1

I would prefer a simple and less nested code like below:

function() 
{
    var duration = +new Date() - start.time,
        isPastHalf = Number(duration) < 250 && Math.abs(delta.x) > 20 || Math.abs(delta.x) > viewport / 2,
        direction = delta.x < 0;

    if (isScrolling)
    {
        return;
    }
    if (isPastHalf) 
    {
        if (direction) 
        {
            this.close();
            return;
        }
        if (this.content.getBoundingClientRect().left > viewport / 2 && pulled == = true) 
        {
            this.close();
            return;
        }
        this.open();
        return;
    }
    if (this.content.getBoundingClientRect().left > viewport / 2) 
    {
        if (this.isEmpty(delta) || delta.x > 0) 
        {
            this.close();
            return;
        }
        this.open();
        return;
    }
    this.close();
    return;
}
