Create a variable called mappedInstruments and assign the value of null. You will assign a value later.

Create a declared function called getMappedInstruments

The function getMappedInstruments does not have any parameters

Within the getMappedInstruments function you will use the $.$map method to map the array of instruments that belongs to the orchestra object.

Remember that the instruments array is a property of the orchestra

The map operation should return an array of objects with only one property:

description : this property should hold the result of concatenating the name and section of the mapped instrument.

Example: if the instrument has a name of trumpet and a section of brass, description should be trumpet brass

The resulting array of the map operation should be assigned to the variable mappedInstruments
