How to rename JSON key

Question

I have a JSON object with the following content:

[
  {
    \"_id\":\"5078c3a803ff4197dc81fbfb\",
    \"email\":\"user1@gmail.com\",
    \"image\":\"some_imag         


        

Answer 1

If anyone needs to do this dynamically:

const keys = Object.keys(jsonObject);

keys.forEach((key) => {

      // CREATE A NEW KEY HERE
      var newKey = key.replace(' ', '_');

      jsonObject[newKey] = jsonObject[key];
      delete jsonObject[key];
   });

jsonObject will now have the new keys.

IMPORTANT:

If your key is not changed by the replace function, it will just take it out of the array. You may want to put some if statements in there.
