推荐答案

此代码将以前的条目替换为新的条目.替换为-

This code replacing previous entry with new entry. Replace this -

dataToImport[department] = {};
dataToImport[department][year] = {}
dataToImport[department][year][course] = {}

与此-

dataToImport[department] = dataToImport[department] || {};
dataToImport[department][year] = dataToImport[department][year] || {}
dataToImport[department][year][course] = dataToImport[department][year][course] || {}
