function sum(...arr){ const total = arr.reduce((acc,val)=>{ if(typeof val === 'number') return acc + val else if(typeof val === 'string') return acc+parseInt(val) else return acc }) return total } console.log(sum(1,2,3, null, '4'))

This doesn't work if an array is passed right? Could you tell me what is the use of spread operator in this?

[@anandkumar-vq2eo]

@@rahulxdd Yes, this will not work if you pass array As per the question they asked here, i wrote the code.

[@onrjs]

Solution: const sum = (...rest) => { const ans = rest.filter(Boolean).reduce((acc, cur) => { if (Array.isArray(cur)) { acc += sum(...cur); } else { acc += parseInt(cur); } return acc; }, 0); return ans; }
