This post talks about 3 ways to convert
Set type to
- forEach loop
- ES6 spread syntax
Use forEach loop to Convert Set to Array
forEach loop is one of the loop syntax to iterate the elements in collections of set type.
Its syntax forEach(callback,[arg]).
the callback is the function that is called for each element of a collection.
It takes three input parameters
- Current element(current element),
- index (index position, optional),
- array (new array called for each element)
const arrayObj = ; mySet.forEach(element=> arrayObj.push(element));console.log(arrayObj); //[ 21, 3, 10 ] console.log(typeof arrayObj); //object
Use ES6 spread new syntax to Convert Set to Array
ES6 introduced spread operator syntax..
Spread operator (..) allows to expand of the collection and expected values of at least one element. It is simple with the spread operator
var mySet = new Set([21, 3, 10,21]); let arrayObj= [...mySet]; console.log(arrayObj);//[ 21, 3, 10 ] console.log(typeof arrayObj); //object
Native from function in array to Convert Set to Array
from() function create and returns a new array from an input iterate collection such as an array, map, or set, and each element is iterated.
Syntax is Array.from(collection of objects);
var mySet = new Set([21, 3, 10,21]); let arrayObj=Array.from(mySet.values()); console.log(arrayObj); //[ 21, 3, 10 ] console.log(typeof arrayObj); //object
