Convert arrays of arrays to object with key

I have arrays of arrays which contains something like this:

var values = [[1, 2, 3], [3, 2, 1]]

I've tried .map() and Object.assign but I dont know how to implement it. I want this as an output:

values = [
 {'up': 1, 'middle': 2, 'down': 3],
 ...
]

What should I use? This is what Im came up so far:

const object1 = [[1,2,3],[3,2,1]],
 object = 

object1.forEach(function(array) 
 object.map(value => ('up': array[0], 'mid': array[1], 'down': array[2]))
 );

console.log(object)

Not very different from what others already did, but a little more elegant:

let arr = [[1, 2, 3], [3, 2, 1]];

let result = arr.map(([up, middle, down]) => (up, middle, down));
console.log(result);

you can simply use Array.map(), there is no need of forEach()

let arr =[[1, 2, 3], [3, 2, 1]];

let result = arr.map((e)=>("up" : e[0], "mid" : e[1], "down" : e[2]));
console.log(result);

var values = [[1, 2, 3], [3, 2, 1]];

if(values.length)
 values.forEach(function(valueArray, index)
 var temp = ;
 valueArray.forEach(function(value)
 if(value == 1)temp.up = value;
 if(value == 2)temp.middle = value;
 if(value == 3)temp.down = value;
 );
 values[index] = temp;
 );


console.log(values);
