// Using slice, create newCar from myCar.
let myHonda = { color: 'red', wheels: 4, engine: { cylinders: 4, size: 2.2 } }
let myCar = [myHonda, 2, 'cherry condition', 'purchased 1997']
let newCar = myCar.slice(0, 2)

// Display the values of myCar, newCar, and the color of myHonda
//  referenced from both arrays.
console.log('myCar = ' + JSON.stringify(myCar))
console.log('newCar = ' + JSON.stringify(newCar))
console.log('myCar[0].color = ' + myCar[0].color)
console.log('newCar[0].color = ' + newCar[0].color)

// Change the color of myHonda.
myHonda.color = 'purple'
console.log('The new color of my Honda is ' + myHonda.color)

// Display the color of myHonda referenced from both arrays.
console.log('myCar[0].color = ' + myCar[0].color)
console.log('newCar[0].color = ' + newCar[0].color)
