getProperty(property: string, object): any

Why would you use this to get a property value instead of simply writing
object[property] or object.property ?
Because this function allows property to be a string that can include dot notation
( i.e, 'property.subproperty.subsubproperty' ) .

Note: even if you are getting the value of an array item, here you need to use
dot-notation and not square braces.
Example: if getting the first item of the first item of an array, write:
getProperty('0.0', array); // instead of array[0][0]

Examples

let officer = {name: {first: 'Tom', last: 'Arnold'}, rank: 'sergeant'};
let lastName = getProperty('name.last', officer);
// lastName === 'Arnold'

let city = {
	name: 'San Francisco', 
	cityCouncil: {
		members: [
			{name: {first: 'Megan', last: 'Trainor'}, age: 26},
			{name: {first: 'Justin', last: 'Bieber'}, age: 85}
		]
	}
};

let ageOfMeganTrainor = getProperty('cityCouncil.members.0.age',  city);
// ageOfMeganTrainor === 26
