js await的函數(shù)，這個(gè)函數(shù)里又有遞歸，還沒有執(zhí)行完就執(zhí)行了

使用 async await來操作函數(shù)異步，函數(shù)體內(nèi)有遞歸，但是遞歸還沒有完成就執(zhí)行完了函數(shù)。then里面的返回值是個(gè)數(shù)組但是數(shù)組打印的長度是1，但真實(shí)長度應(yīng)該是5，打斷點(diǎn)調(diào)試res的第一個(gè)返回值是一個(gè)長度為1的數(shù)組，但是緊接著就是長度為5的數(shù)組，await不是應(yīng)該等getAllDownRoteEquipment函數(shù)執(zhí)行完了再返回值嗎？請(qǐng)求大神解答
