Hi! This works perfectly fine on my Atom console, but somehow only throws errors (.entries() is not a function) if I attempt.

function cakes(recipe, available) {
return Object.entries(recipe)
.map( (e, i, a) => Object.entries(available).some( (x, y, z) => z[y][0] === a[i][0])
? Object.entries(available).find( (x, y, z) => z[y][0] === a[i][0])[1] / a[i][1]
: 0
)
.sort()
.slice(0, 1)
}
