javascript - How to build a Firestore query chain based on a dynamic response from a promise

Question

Let's say I need to query Firestore against a collection of subjects that I receive in a promise:

const subjects: string[] = await getSubjects(); //response: ['Math', 'Science', 'History'];

Since I don't know how many subjects might be returned in the promise at any given time, how would I go about dynamically generating the chain below so I can properly query Firestore?

ref.where('subject[subjects[0].toLowerCase()]', '==' , true)
    .where('subject[subjects[1].toLowerCase()]', '==' , true)
    .where('subject[subjects[2].toLowerCase()]', '==' , true);

The more subjects that are returned, the more .where() methods it would need to generate.
