Filter array by Object key

Question

I have an array that looks like

const arr = [
{img2: "assets1.png - Copy.png"},
{img2: "lime.jpg"},
{img2: "ginalee.jpg"}
{img2: "cb.jfif"}
{code: "blob:http://localhost:3000/d2c4641a-8586-4bb8-9a14-21b6712856ff", key: "img2", value: "cb.jfif"}
{code: "blob:http://localhost:3000/b406ceb8-92f4-4bbd-9eef-7db7d103b1e3", key: "img2", value: "lime.jpg"}
{code: "blob:http://localhost:3000/28130041-347f-49d9-b30d-72e26c9a6dda", key: "img2", value: "ginalee.jpg"}
{code: "blob:http://localhost:3000/d0d3e9aa-8791-419d-8585-f6c878b161e6", key: "logo", value: ""}
{code: "blob:http://localhost:3000/187977de-6a8f-4815-b3e2-01bfa818bcb7", key: "logo", value: "OIPYYPYPEVF.jpg"}
{code: "blob:http://localhost:3000/dee69b85-6d13-4f81-ba5b-d8db5708d9c8", key: "logo", value: ""}
{code: "blob:http://localhost:3000/676b0366-f30e-4653-9716-ab0ebf4155a2", key: "logo", value: "image (
5).png"}
]

I need to get rid of the ones that say img2 (or really /img[0-9]/) and just about every variation of

arr.filter((f)=>Object.keys(f).includes(...)) isn't working.

any help would be great.

Check if .some of the keys contain img:

arr.filter(obj => Object.keys(obj).some(key => !key.includes('img')))

for(let i = 0; i < arr.length; i++) { 
  for(let r in arr[i]) { 
     if(arr[i][r].match(/(img)[0-9]/ig)) { 
        arr[i][r] = arr[i][r].replace(/(img)[0-9]/ig, "");
      }
   }
}
console.log(arr);

Something like this could work to ignore all img[0-9]:

arr.filter((val) => Object.keys(val).every((key) => !key.match(/^img[0-9]+$/i)));

This will get all the keys for each individual object and evaluate with every if the key name matches the regex to get the negated value (meaning any value matching the regex will return false causing .every to stop iterating and return false to the .filter function and thus removing those values.
