  Please write a function that checks if two objects have the same content.
*/
/* NOTES:
  1. Ignore _id.
  2. Keys in the objects are unknown to this function.
      Please don't do:
                  offerA.rate equals offerB.rate and
                  offerA.offerType equals offerB.offerType
                ...etc
  3. Write smaller functions if necessary and name them well.
  4. Write comments if necessary.
  5. Below are the two objects we want you to compare and the result should be true.
  6. WHEN COMPLETE, ACTIONS -> SAVE PRIVATE GIST, AND INCLUDE THE LINK IN THE WRITTEN INTERVIEW.
