How Can A Key Be Removed From A JavaScript Object?

To remove a key from a JavaScript object, you can use the delete keyword. Here’s an example:

let obj = {
  key1: "value1",
  key2: "value2",
  key3: "value3"

delete obj.key2;

console.log(obj); // { key1: "value1", key3: "value3" }

In the example above, the delete keyword is used to remove the key2 from the obj object. The resulting object obj will no longer contain the key2.

Note: It’s important to keep in mind that using delete on an object does not reindex the remaining keys. The other keys remain unchanged, and any subsequent iteration over the object will not include the removed key.
