Tests:

  • Set delete

     
    const arrOrg = new Array(1000).fill(() => 'Nei');
    const arr1 = arrOrg.map(() => () => 'Nei');
    const arr2 = arrOrg.map(() => () => 'Nei');
    const func = () => console.log('Hei!');
    const set = new Set([...arr1, func, ...arr2]);
    set.delete(func);

  • Array splice

     
    const arrOrg = new Array(1000).fill(() => 'Nei');
    const arr1 = arrOrg.map(() => () => 'Nei');
    const arr2 = arrOrg.map(() => () => 'Nei');
    const func = () => console.log('Hei!');
    const set = [...arr1, func, ...arr2];
    const index = set.indexOf(func);
    set.splice(index, 1);
