// Map Example

const a = new Map();
const b = {};

//Adding key-value pairs
console.log("Set Key");
//Map
a.set('test', 3);
console.log(...a.entries()); //[ 'test', 3 ]
//Object
b['test'] = 3;
console.log(b); //{ test: 3 }
//Get key
console.log("\nGet Key");
//Map
const c = a.get('test');
console.log("Map:", c);//Map: 3
//Object
const d = b['test'];
console.log("Object:", d); //Object: 3


//Has key
console.log("\nHas Test");
//Map
console.log("Map:", a.has('test')); //true

//Object
console.log("Object:", b['test'] !== undefined); //true (But could be set to null or undefined by developer)

//Remove key
console.log("\nDelete Key");
//Map
console.log("Map:", a.delete('test')); //true if there is a key to remove
console.log("Map:", a.get('test')); //Map: undefined
//Object
delete b['test'];
console.log("Object:",b['test']); //Object: undefined
