| I know exactly where this is from. This has been floating around the Chinese Internet for a bit. The repo is originally at https://github.com/wheatup/evil.js but has been made private since then. A few variants of this was made and uploaded to NPM. Here's a English translation of the README.md in that specific repo. > What? The notorious 996 company wants you to hit the road? > > Do you want to leave a small "gift" for your project before you go? > > Let's sneak this project into yours, and your project will have, but not limited to, the following magical effects: > > - When the length of the array is divisible by 7, Array.includes will always return false. > - When it's Sunday, the result of the Array.map method always loses the last element. > - There is a 2% chance that the result of Array.filter will lose the last element. > - setTimeout will always trigger one second slower than expected. > - 10% of Promise.then will not register on Sundays. > - JSON.stringify will change uppercase I to lowercase l. > - The result of Date.getTime() will always be one hour behind. > - There is a 5% chance that localStorage.getItem will return an empty string. see: https://juejin.cn/post/7133134875426553886 |
