// Our data
const fruits = {
apple: {
qty: 300,
color: "green",
name: "apple",
price: 2
},
banana: {
qty: 130,
color: "yellow",
name: "banana",

color: "orange",
name: "orange",
price: 1.5
},
melon: {
qty: 70,
color: "yellow",
name: "melon",
price: 5
}
};
// Now let"s create a map function
const map = (obj, fun) =>
Object.entries(obj).reduce(
(prev, [key, value]) => ({
...prev,
[key]: fun(key, value)
}),
{}
);
// Finally let's map by color for example
const myFruits = map(fruits, (_, fruit) => fruit.color);
/*
{ apple: 'green',
banana: 'yellow',
orange: 'orange',
melon: 'yellow' }
