• assertArraysEqual(arr1, arr2): Takes in 2 arrays and returns true if they are equal and false otherwise.

• assertEqual(x, y): Takes in 2 values and returns true if they are equal and false otherwise

• assertObjectsEqual(obj1, obj2): Takes in 2 objects and returns true if they are equal and false otherwise
