Merge objects using jq

Given a file named example.json

{
    "key": "value1",
    "anotherKey": "value2",
    "oneMoreKey": "value3"
}

and another file named example2.json,

1
2
3
4
5

{
  "key1": "value2",
  "key2": "value3",
  "key4": "value4"
}

merging the two objects can be completed using:
