Array and Object Manipulation

const games = [
    { title: 'halo', year: '2001' },
    { title: 'metroid', year: '1986' },
    { title: 'contra', year: '1987' },
    { title: 'overwatch', year: '2016' },
    { title: 'uncharted', year: '2007' }

// how do we list these by year?

// 1. declare an empty array to use as our 'scratch-pad'
let sortableGames = []

// 2. for each item in the list of games, grab the title and year then push it into our empty array
games.forEach(game => {
    sortableGames.push([game.title, game.year])
})

// 3. declare a function to perform the comparison between year values
// gameA[0] = title, gameA[1] = year
function compareYear(gameA, gameB) {
    return gameA[1] - gameB[1]
}

// 4. declare a new variable containing our results
const sortedGames = sortableGames.sort(compareYear)

// 5. convert the sorted items back into objects
let orderedGames = []

sortedGames.forEach(game => {
    orderedGames.push({ title: game[0], year: game[1] })
})

// Log the results
console.log(orderedGames)
