Easier way to filter data












0















I'm trying to figure out a faster way to filter the tags below instead of using map three times.



I've looked a bit at loadash and their filter function. But doesn't seem to help speed wise.



export function tagFilter(reviews, userTags) {

const arr = ;

map(reviews, (review) => {

let count = 0;

map(review.tags, (tag) => {
map(userTags, (userTag) => {
if (userTag.tag_data.id === tag.id) count += 1;
});
});

arr.push({ review, count });

});

arr.sort((a, b) => b.count - a.count);

const reviewArray = ;

arr.forEach((reviewObject) => {
reviewArray.push(reviewObject.review);
});

return reviewArray;
}


Any suggestions is highly appreciated?

map, loop, for loop and lodash map from this looping option the fastest is lodash map so i am sure about this you have to use lodash for map no other looping library is faster then lodash



Here are a comparation of the native map against the lodash map
https://jsperf.com/native-map-vs-lodash-map



Aparently lodash is faster
