Unusual control structures cause us all to slow down a little.
Maybe I'm tired, but I had one of those moments today where something seemed to make a lot of sense and you just had to tell someone about it. So here you go.

- goplexian 17y agoThanks, yes. Fixed.
- JshWright 17y agoI think the particular example given has less to do with the fact that do...while is a less common control structure, and more with the syntax of do...while itself. I suspect the referenced "slow down" was that the reader will naturally, upon encountering a loop, scroll to the end of the loop and figure out what the conditional is. Obviously the isn't really necessary in a do...while, since that code's going to run once no matter what, but I suspect most of us still do it anyway (like looking both ways before crossing a one way street).
- RyanMcGreal 17y agoI've been musing over some of these same ideas since reading Crockford's Javascript: The Good Parts over Christmas break. He certainly makes a strong case for Javascript that it's better to become intimately acquainted with a sensible, well-designed, and mostly gotcha-free subset of the language rather than go crawling into its margins in pursuit of elegance.
