Why Array.reduce() is needed in Array remove when we can get the same result using just Array.filter()?

[vivek28111992]

Why array reduced is used?

const remove = (arr, func) => Array.isArray(arr) ? arr.filter(func).reduce((acc, val) => { arr.splice(arr.indexOf(val), 1); return acc.concat(val); }, []) : [];

as we can get the same result using this

const remove = (arr, func) => Array.isArray(arr) ? arr.filter(func) : [];

Can anyone please answer this?

This is done to remove duplicate elements from the final result.
