• assertEqual(value1, value2): takes in 2 values and returns true if they are equal and false otherwise;
• eqArrays(arr1, arr2): takes in 2 arrays and returns true if the arrays are equal and false otherwise;
• assertArraysEqual(arr1, arr2): prints an appropriate message after comparing the two arrays;
• without(sourceArr, itemsToRemove): takes in a source array and an itemsToRemove arrays and returns only the items from the source array that are not in the itemsToRemove array.,
