所以我有了这个过滤器，我试图弄清楚是否可以更轻松/更好地进行此操作。感觉我重复了很多次。我想将所有数字放入一个数组，然后使用该数组进行过滤。
那么我可以使用包含所有数字的数组来做到这一点吗？就像是
var filterIDs = [2, 3, 5, 6, 8, 9, 31, ...]
而不是一些代码？我只是不知道如何。
目前可以使用，但感觉很笨拙且重复。
let filterPokemonRare = list.filter(function (f) {
return f.pokemon_id == 2 || //Ivysaur
f.pokemon_id == 3 || //Venusaur

您可以使用一个数组，并检查该数组是否包含pokemon_id。
它与箭头功能配合使用，对所需属性进行破坏性 分配 ，并Array#includes检查pokemon_id元素是否为数组的元素filterIDs。
var filterIDs = [2, 3, 5, 6, 8, 9, 31 /* ... */],
filterPokemonRare = list.filter(({ pokemon_id }) => filterIDs.includes(pokemon_id));
