现在有两个数组：

moudlesArray = [
    ['a','b']
    ['c'] 
    ['d','e'],
    ['f'],
    ...
]
data = [
    {name:'a'}, 
    {name:'b'},
    {name:'c'},
    {name:'d'},
    {name:'e'},
    {name:'f'},
    ...
]

目标数组：

res = [
    [{name:'a'},{name:'b'}],
    [{name:'c'}],
    [{name:'d'},{name:'e'}],
    [{name:'f'}]
    ...
]

回答：

const dict = Object.fromEntries(data.map(obj => [ obj.name, obj ]))
moudlesArray.map(item => item.map(name => dict[name]))

不知道是不是顺序也一样，如果是的话

; (i => moudlesArray.map(item => item.map(() => data[i ++])))(0)
