the end of a saga rip

This is the long awaited part 4 to the HTML How to Create a Cookie Clicker Website. Within this episode we will be looking at the multiplier upgrade.
I mention ending the series with the next episode, but after some thinking I’ve got a few more ideas to add mainly relating to its target rewritten below.
Part 3:
Part 5: Not Yet Out

Within this series we will slowly create a cookie clicker styled website with features like unlockables for progression, achievement popups, and some CSS styling to spice the site design up.

  1. Thank you for this amazing tutorial! 😀

  2. Sorry for delays guys uploads will be back on track now! Feel free to post any questions related to the video or issues you are having with your code.

  3. Okay, One last comment (Sorry for basically filling your comment section) but if you were to do a new series, I have a suggestion. So, if we are staying on coding then a multiplayer .io series would be nice. But, as I have kinda looked into it, Multiplayer is difficult to make, so how about you vs a robot with chess/checkers??? Just in case those are too hard/don't appeal to you, how about a platformer? Still no? Well, how about a city builder game? Okay I'm almost out of ideas, one more, how about a Telltale games type of game where your decision affect things later on? Okay that last one was a stretch but lemme just say City Builder/Chess/Checkers game appeals to me. Like if you agree because so far I think i'm the only one who likes chess/checker bots and city builders. I dunno. Thanks for all the hard work that you do to bring these videos to us! 'Preciate it!

  4. Finally. Time to get your Mcflurry boiiiii

  5. Tbh could have figured it out myself by the time it took you to upload

  6. Can someone get me the full finished code as of now, because I keep screwing up and I'll have to rewatch the vid a hundred times :/

  7. I like how you said "It should take about a week hopefully" for the next episode and its been more than 3 months. I wanna see more!

  8. for some reason, if you click the multiplier again without the correct amount of money, it goes into the negatives. how do i fix??

  9. Well damn. A year already? I hope you're doing well. Over the last year, I've gotten better at coding by a lot. How I learned was from experimenting around with code and trying new things on my own. I think you should encourage viewers to do this, because well, it's how you learn. I really love the HTML language, and hopefully part 5 will come out eventually and I can keep learning. Or, y'know, any Leeson Reviews… Basically any content. Thanks!

  10. can somebody please send me the final code i keep failing

  11. My working version :
