pLimit giving me a list of undefined promises

Question

        const maxParallelRequests = 1;
        const limit = pLimit(maxParallelRequests);

        // Use the map method to create an array of promises for each call to GetData
        const promises = items.map(item => {
            limit(() => this.getData(item))
        });

When I log promises I get an array of 60 undefined items.

What am I doing wrong here?

item is defined inside the map function.

Answer 1

I had to add return in the map:

        // Use the map method to create an array of promises for each call to GetData
        const promises = items.map(item => {
            return limit(() => this.getData(item))
        });
