Map ↔ Object 변환

Object.entries(Object), Object.fromEntries(Map)를 통해 Map과 Object간 변환이 가능 

let recipe_juice = new Map([
    ["strawberry", 50],
    ["banana", 100],
    ["melon", 150],
]);

console.log(recipe_juice);

let recipe_juice_obj = Object.fromEntries(recipe_juice);
let recipe_juice_kv = Object.entries(recipe_juice_obj);

console.log(recipe_juice_obj);
console.log(recipe_juice_kv);
