Can I return a push() directly?

JavaScript

Tell us what’s happening:
May I know why the second scenario doesn’t yield the same output as the first scenario? Why is it necessary to execute separate lines for the push to be returned? And also why would the second scenario yield an output of 3?

   **Your code so far**


function test(param1, param2) {
  param1.push(param2);
  return param1
}
console.log(test(["cat", "dog"],'duck'))       //display [ 'cat', 'dog', 'duck' ]


function test2(param3, param4) {
  return param3.push(param4);
}
console.log(test2(["cat", "dog"],'duck'))      //display 3

push method returns the new length of the array.
