如何根据A数组将B数组组装为新数组？-灵析社区
我爱了你呢let A = ['A', 'B', 'C'] let B = [ ['1A'], ['2A','2C'] ] 根据 A 数组将 B 数组组装一个新数组 newArr = [ ['1A', null, null], ['2A', null, '2C'] ] 我要的新数组 newArr = [ ['1A', null, null], ['2A', null, '2C'] ]
LightSeaconst conv = (schema, source) => source.map(a => {
const dict = {}
a.forEach(i => {
const name = i.at(-1) // 没有给出具体的数据格式，假定和 A 匹配的字符串就是最后一位
dict[name] = i
})
return schema.map(name => dict[name] ?? null)
})
