For Workers & Pages, what is the name of the domain?
lingben.chiziingiin.top
What is the issue or error you’re encountering
When we used the Array.map((e)=>{}) function of JavaScript in workers, we found that cloudflare may not implement this function according to the standard. According to the JavaScript specification, using the map function will not change the original array, but the workers environment changes the original array. This problem can be easily reproduced. This bug has caused me great trouble. I hope you will pay attention to it and fix it. Thank you. Reference standard Array.prototype.map() - JavaScript | MDN
What steps have you taken to resolve the issue?
I avoid using the map function
