recursive filter for lists; Is this any good?

recursive_filter.ts

interface FilterListEntry {
    listId: String,
    name?: String
}

export class test_filter_class{
    
    // unfilterCompanies = [comp_ids]
    // eg. unfilterCompanies = [123,456,789]
    
    private apply_filter = async (filterInfo: Array<FilterListEntry>, unfilterCompanies: any) => {
        if(filterInfo.length == 1){
            let filterInfoEntry = filterInfo.pop();
            let filterList = await MailingListCompany.find({ "mailingList": filterInfoEntry.listId })            
                .lean();

            let filterData = await MailingList.findById(filterList[0].mailingList);

            let theFilter = filterList.map((e) => { return e.company });
            let yesInFilter = unfilterCompanies.filter((el) => theFilter.includes(el._id));
            let notInFilter = unfilterCompanies.filter((el) => !theFilter.includes(el._id));

            yesInFilter.forEach((e) => {
                e[`${filterData.name} filter`] = true
            });

            return [...yesInFilter, ...notInFilter]
        } else {
            let filterInfoEntry = filterInfo.pop();
            let filterList = await MailingListCompany.find({ "mailingList": filterInfoEntry.listId })            
                .lean();

            let filterData = await MailingList.findById(filterList[0].mailingList);

            let theFilter = filterList.map((e) => { return e.company });
            let yesInFilter = unfilterCompanies.filter((el) => theFilter.includes(el._id));
            let notInFilter = unfilterCompanies.filter((el) => !theFilter.includes(el._id));

            yesInFilter.forEach((e) => {
                e[`${filterData.name} filter`] = true
            });

            return this.apply_filter(filterInfo, [...yesInFilter, ...notInFilter]) 
        }
    }

}

If the code inside the if..else are similar except for the return, perhaps rewrite it to this?

export class test_filter_class{
    
    private apply_filter = async (filterInfo: Array<FilterListEntry>, unfilterCompanies: any) => {
        if (filterInfo.length == 1) { return [...yesInFilter, ...notInFilter] }
     
        let filterInfoEntry = filterInfo.pop();
        let filterList = await MailingListCompany.find({ "mailingList": filterInfoEntry.listId })            
            .lean();

        let filterData = await MailingList.findById(filterList[0].mailingList);

        let theFilter = filterList.map((e) => { return e.company });
        let yesInFilter = unfilterCompanies.filter((el) => theFilter.includes(el._id));
            let notInFilter = unfilterCompanies.filter((el) => !theFilter.includes(el._id));

            yesInFilter.forEach((e) => {
                e[`${filterData.name} filter`] = true
            });

            return this.apply_filter(filterInfo, [...yesInFilter, ...notInFilter]) 
        
    }

}
