I'm considering two different approaches and I'm unsure which one is recommended in terms of readability and memory allocation. From my understanding, both have the same space complexity as they both use some form of storage (two variables in the first approach and an accumulator in the reduce method). Can you advise on which approach is preferable?
Approach 1:
const getFilters = () => {
const filters1 = [];
const filters2 = [];
// assuming 'filters' is an array of numbers
filters.forEach(filter => {
if(filter === 1) {
filters1.push(filter);
} else {
filters2.push(filter);
}
})
return {
filter1: filters1,
filter2: filters2,
}
}
Approach 2:
const getFilters = () => {
// assuming 'filters' is an array of numbers
return filters.reduce(
(accumulator, filter) => {
if (filter === 1) {
accumulator.filters1.push(filter);
} else {
accumulator.filters2.push(filter);
}
return accumulator;
},
{
filters1: [],
filters2: [],
},
);
}
