const score = (lead) =>
  FACTORS.map((factor) => lead.attr(factor))
    .map((x) => x.coalesce(0))
    .reduce((l, r) => l.add(r));

const TopLeads = Leads
  .innerJoin(Companies, (lead, company) => ({
    on: Eq(company.attr('id'), lead.attr('company_id')),
    select: {
      ...lead.renameWith((oldName) => `lead_${oldName}`),
      ...company.pick('num_employees', 'revenue'),
      LEAD_SCORE: score(lead),
    },
  }))
  .where((t) => t.attr('LEAD_SCORE').gte(15));
