Return resolved promise

Question

I have a function in my strapi where I map the data and run another query inside.

async search(ctx) {
    const authors = [
        {
            id: 1,
            name: "author 1"
        },
        {
            id: 2,
            name: "author 2"
        },
    ]

    authors.map((data, i) => {
        var books = this.getBooks(data.id)
        console.log(books)

        // some stuffs here
    })
},

getBooks: async function (authorId) {
    return await strapi.query('books').find({ userId: authorId })
}

The console.log('books') display Promise { <pending> }. I'm not very familiar with the promise stuff but I tried something like below but guess it's not the right way. It's still returning the same promise pending.

getBooks: async function (authorId) {
    const books = await strapi.query('books').find({ userId: authorId })
    return Promise.resolve(books)
}

If I return just books, that has no difference with the original function I have in the first code block. — Emerald, Feb 23 '21 at 11:43

Found this discussion here . It appears that map doesn't work with promises. I switched to for loop as mentioned in the discussion and it's working now.

async search(ctx) {
    const authors = [
        {
            id: 1,
            name: "author 1"
        },
        {
            id: 2,
            name: "author 2"
        },
    ]

    for (let data of authors) {
        const books = await strapi.query('books').find({ userId: data.id })
        console.log(books)

        // some stuffs here
    }
}
