Set delete

const arrOrg = new Array(1000).fill(() => 'Nei');
const arr = arrOrg.map(() => () => 'Nei');
const func = () => console.log('Hei!');
const set = new Set([...arr, func]);
set.delete(func);

 
const arrOrg = new Array(1000).fill(() => 'Nei');const arr = arrOrg.map(() => () => 'Nei');const func = () => console.log('Hei!');const set = new Set([...arr, func]);set.delete(func);

Array splice

const arrOrg = new Array(1000).fill(() => 'Nei');
const arr = arrOrg.map(() => () => 'Nei');
const func = () => console.log('Hei!');
const set = [...arr, func];
const index = set.indexOf(func);
set.splice(index, 1);
