我有这个对象数组，里面还有其他数组。每个对象都是一个partner，每个伙伴都有1个或几个industries和solutions。
我首先想做的是通过选定的partners过滤industry。例如，如果选择的下拉列表为Agency，那么我只想显示在其代理商价值内具有Agency作为选项的合作伙伴。
我对specialty的操作与此类似，但是我只能与之抗衡
export function getBySpecialty(partners, specialty) {
if (!specialty) return partners
return partners.filter(partner => partner.specialty === specialty)
}
如何为嵌套数组实现相同的目的？

尝试一下：
export function getByIndustry(partners, industryTitle) {
if (!industryTitle) return partners
return partners.filter(partner => partner.industries.filter(industry => industry.title === industryTitle).length)
}

走了
export function getByIndustry(partners, industry) {
if (!industry) return partners
return partners.filter(partner => partner.industries.some(ind => ind.title === industry))
.map(partner => partner)
}
