JavaScript Set remove | Example code

  • by

You have to use the delete method to remove the element form set in JavaScript. This method removes a specified value from a Set object, if it is in the set.


If the value exists in the Set, it gets removed from the Set object and true is returned, otherwise the method returns false.

JavaScript Set remove

Simple example code passes the value to delete from the set.

<!DOCTYPE html>
    const s = new Set([1,2,3,4]);





JavaScript Set remove

If you need to delete an object or array from a Set, you need to have a reference to the object / array, or use the forEach method to get a reference.

const set1 = new Set([{id: 1}, {id: 2}]);

set1.forEach(obj => {
  if ( === 2) {

console.log(set1); // 👉️ { {id: 1} }

If you have a direct reference to the object, there’s an easier way to do this.

const obj = {id: 1};
const set1 = new Set([obj, {id: 2}]);


console.log(set1); // 👉️ { {id: 2} }
