i have done using reduce Output => result[0] = unique, result[1] = repeated;
const result = a.reduce((acc, current) => { const has = acc[0].some((ele) => ele === current); if(has) { const _has = acc[1].some((ele) => ele === current); if(!_has) { acc[1] = [...acc[1], current]; } } else { acc[0] = [...acc[0], current]; } return acc; },[[], []]);
// [ [4,3,6], [4,3] ];
