///We have an array of objects representing different people in our contacts lists.

//A lookUp function that takes firstName and a property (prop) as arguments has been pre-written for you.

//The function should check if firstName is an actual contact's firstName and the given property (prop) is a property of that contact.

//If both are true, then return the "value" of that property.

//If firstName does not correspond to any contacts then return "No such contact"

//If prop does not correspond to any valid properties then return "No such property"
