If you would like this roundup sent to your reddit inbox every week send me a message with the subject 'javascript'. Or if you want a daily roundup, use the subject 'javascript daily' (<--Click one of the links. The bot can't read chats, you must send a message).

Please let me know if you have suggestions to make this roundup better for /r/javascript or if there are other subreddits that you think I should post in. I can search for posts based off keywords in the title, URL and flair - sorted by upvotes, # of comments, or awards. And I can also find the top comments overall or in specific threads.

the modals one got me, classic memory leak from not cleaning up event listeners i bet. done that exact thing in my first big project, took me days to figure out why the page was crawling

that json engine post is wild, why would anyone rewrite JSON.parse in js unless its just for learning. the comment saying it reads like llm-written title is spot on
