js - sets

// Set : stores unique values

// initialising an empty set

const mySet = new Set();

// adding vlaues in set

mySet.add('this')

mySet.add({key : "value"})

mySet.add(35)

mySet.add(true)

mySet.add('this')//cant take repeated values

mySet.add("gone case") 

// console.log(mySet);

// Using constructor to initialize the set

// const mySet2 = new Set([1,24,'this',false,{a:4 , b:'hello'},'this'])

// console.log(mySet2);

// getting size of set

// console.log(mySet.size);

// checking value exist in set or not

// console.log(mySet.has(35));

// removing value from set

// console.log("before removal",mySet);

// console.log(mySet.delete('gone case'));

// console.log("after removal", mySet);

// iterate the set

// for(let item of mySet){

// console.log(item);

// }

// using forEach loop

// mySet.forEach(element => {

//     console.log(element);

    

// });

// convertin set to array

// let mySetArray = Array.from(mySet);

// console.log("ARRaY of set", typeof(mySetArray));

// console.log("ARRaY of set", mySetArray);

/* example : removing duplicates from Array

array with duplicates

let newArray = [34,23,'this','hello', {a : 5,b: 6},'this']

console.log("Array with duplicate ", newArray);

/converting array to set

var myArraySet = new Set(newArray);

 converting set back to array with duplcates removed

let newArray2 = Array.from(myArraySet);

console.log("Array with duplicates removed ", newArray2);
