    Also managed to increase the time to understand the code from 5 to 60 minutes

    Also, unless you're running that code a couple hundred times then the time saving is basically negligible.

    @BadFox any optimization is good optimization

    @MrJimmy be careful with what you learn. If you learn regex now, you might have to use it some day!

    @beegC0de perhaps, although maybe not for small systems. I can see the use in a system like the internet where 1 ms is massive but in something like a video conversion, 1ms off the conversion time isn't a lot.

    @MrJimmy I see "Mr" and I see female avatar. I think to myself "something doesn't add up". Then, I shrug and move on. It's devRant, we're a different people.

    @BadFox well yeah obviously 1ms off an entire transcode is negligible. He got his code to go 6 times faster which isn't negligible.

    @beegC0de yes, I know. It went on a tangent. What I meant is, in that case the difference between a total execution time of 60ms Vs 5ms isn't likely to be noticed unless the program is ran several hundred times.

    @BadFox well if it ever needs to be run repeatedly it's optimised 8)

    But isn't regex itself just an algorithm? So just means their implementation of loop is more efficient than yours?

    @billgates its 1 of 2 things... a seried of more efficient loops... or black magic

    Crap... I feel I need to invest more time in regex than I have previously had.
