javascript - JS one-liner filter similar objects from 2 arrays -


i'm trying filter 2 arrays have similar objects.

genrefiltered returns correctly

sortfiltrered should return aray 5 objects recommended array.
instead returns empty.

can spot what i'm doing wrong way i'm filtering 2 arrays in sortfiltrered? 

let genrefiltered = genrevalue !== 15 ? games.filter((game) => game.genre_id === genrevalue) : games  let sortfiltrered= sortvalue !== 1 ? genrefiltered.filter((game) => game.game_id === recommended.filter((rec) => rec.game_id)) : genrefiltered  console.log('recommended', recommended) console.log('genrefiltered', genrefiltered) console.log('sortfiltrered', sortfiltrered)

output:

enter image description here

it can't equal ... should @ least first element.

let agefiltrered = sortvalue !== 1 ? genrefiltered.filter((game) => game.game_id === recommended.filter((rec) => rec.game_id)[0].game_id)

that code filter have game_id, , check first ocurrence.

if want not check first occurence can (it simple example can use in case):

var arr = [{w:'2'}, {w:'3'}, {w:'12'}, {w:'456'}] arr.filter(w => w.w.indexof(arr.filter(w => w.w === '22').map(w => w.w).join()) !== -1)
