目前，RealmJS只支持查询对象列表，但我们计划添加对查询基本类型列表的支持。在此之前，您可以使用以下内容：

const Realm = require('realm');

const BookrackSchema = {
    name: 'Bookrack',
    properties: {
        book_names:'string[]',
    }
};

let realm = new Realm({schema: [BookrackSchema]});

realm.write(() => {
    realm.create('Bookrack', { book_names: ['A','B','C']});
    realm.create('Bookrack', { book_names: ['B','C','D']});
    realm.create('Bookrack', { book_names: ['C','D','E']});
});

let objs = realm.objects('Bookrack');
let Bs = objs.filter(obj => { return obj.book_names.reduce((acc, cur)  => { return acc || cur === 'B' }, false)});

目前任何绑定都不支持它。如果你感到不安，就在这里下地狱：

aResult:The keypath following 'ANY' or 'SOME' must contain a list

bResult:Object type 'Table' not supported

const Realm = require('realm');

const BookrackSchema = {
    name: 'Bookrack',
    properties: {
        book_names:'string[]',
    }
};

let realm = new Realm({schema: [BookrackSchema]});

realm.write(() => {
    realm.create('Bookrack', { book_names: ['A','B','C']});
    realm.create('Bookrack', { book_names: ['B','C','D']});
    realm.create('Bookrack', { book_names: ['C','D','E']});
});

let objs = realm.objects('Bookrack');
let Bs = objs.filter(obj => { return obj.book_names.reduce((acc, cur)  => { return acc || cur === 'B' }, false)});
