JavaScript: Convert Set to Array

There are three ways to convert a set to an array

a.   Using Array.from method

b.   Using Spread operator

c.   Manually inserting the elements from set to array

Using Array.from method

HelloWorld.js

var countries =  new Set();

countries.add("India");
countries.add("Australia");
countries.add("Canada");
countries.add("Germany");

var arr = Array.from(countries);

console.log(arr);

Output

Array(4) [ "India", "Australia", "Canada", "Germany" ]

Using Spread operator

Example

var arr = [...countries];

HelloWorld.js

var countries =  new Set();

countries.add("India");
countries.add("Australia");
countries.add("Canada");
countries.add("Germany");

var arr = [...countries];

console.log(arr);

Output

Array(4) [ "India", "Australia", "Canada", "Germany" ]

Manually inserting the elements from set to array

var arr = new Array()

for(var ele of countries){

  arr.push(ele);

}

HelloWorld.js

var countries =  new Set();

countries.add("India");
countries.add("Australia");
countries.add("Canada");
countries.add("Germany");

var arr = new Array()

for(var ele of countries){
  arr.push(ele);
}

console.log(arr);

Output
Array(4) [ "India", "Australia", "Canada", "Germany" ]
