Answer 1

You can use Array#reduce to split the array:

const total = ["10%", 1000, "5%", 2000];

const { absolute, percentage } = total.reduce((arrs, item) => {
  const key = typeof item === 'number' ? 'absolute' : 'percentage';
  
  arrs[key].push(item);
  
  return arrs;
}, { percentage: [], absolute: [] });

console.log(absolute);

console.log(percentage);
