Imperative VS Declarative
# Imperative
const people = ['Amanda', 'Geoff', 'Michael', 'Richard', 'Ryan', 'Tyler']
const excitedPeople = []
for (let i = 0; i < people.length; i++) {
excitedPeople[i] = people[i] + '!'
}
# Declarative
const people = ['Amanda', 'Geoff', 'Michael', 'Richard', 'Ryan', 'Tyler']
const excitedPeople = people.map(name => name + '!')
