#Javascript

I made a Jack-o‘-Lantern carving game with my son. Give it a whirl for a bit of spooky fun, and have a Happy Halloween this weekend!

I came across jsfuck. It shows you how to write any JavaScript code using only []()!+. For example alert(1) would become:

[][(![]+[])[+[]]+([![]]+[][[]])[+!+[]+[+[]]]+(![]+[])[!+[]+!+[]]+(!![]+[])[+[

And it is the best summary of the Javascript brand that I've ever seen.

"As of October 26, 2026, Rapid7 is not aware of exploitation in the wild, and CVE-2026-111497 is not listed in CISA's Known Exploited Vulnerabilities catalog. However, given the vulnerability's potential to disclose memory or enable remote code execution (RCE), Rapid7 recommends that organizations prioritize remediation."

Cloudflare has a new announcement. And judging by the first quote, the bots will be doing the checking?

"Our goal is to help developers spend less time waiting for their code to be checked and more time building. Making TypeScript faster and more memory-efficient also helps bring complete development environments to more places, including right in your browser."

"To be clear, we are not forking TypeScript. We believe the TypeScript team should remain in full control of the language’s design and direction. They have maintained a long-term vision while guiding TypeScript’s adoption across the JavaScript community. We do not want to change that."

Hey, #FediHelp #FediAdvice

TL;DR looking for websites for freelancing for Front End Development.

Any Front End JavaScript Developers using sites where you can pitch for freelance work?

I seemed to have signed up to a couple recently that I am not super impressed with.

I used to use peopleperhour.com although it was quite varied in terms of quality and $ some clients were willing to offer. PPH tried to bring people in line.

Anyway here are some with some descriptors.

Twine

• Worldwide
  • Uses AI
  • Has a subscription model/Free tier is limited

xing.com

• Worldwide?
• Uses AI?
• Has a subscription model/Free tier is limited. (I have still yet to complete my profile on here, which I think is somewhat damning)

People per hour

• Worldwide
• Some bad pricing_ No longer free (seems like this one has gone down the pan).

Any others? I was happy to look to go back to PPH, but not anymore.

Would ideally like something UK centric, or with a heavy UK basis, no AI and ideally not a paid tier model.

(Feel free to retoot for more reach)
