How can I get permutations of many different arrays with different number of values in them?

I read this medium article and I understand how to get permutations of values in one array. However I need to get the permutations of dynamically entered arrays. I want to make an app where I have multiple fields where I can enter multiple arrays with many values in them and I want to get all permutations after storing them.

How can I get permutations of many different arrays with different number of values in them following the principles in this code?

      function permute(nums) {
            let result = [];
            if (nums.length === 0) return [];
            if (nums.length === 1) return [nums];
            for (let i = 0; i < nums.length; i++) {
                const currentNum = nums[i];
                const remainingNums = nums.slice(0, i).concat(nums.slice(i + 1));
                const remainingNumsPermuted = permute(remainingNums);
            for (let j = 0; j < remainingNumsPermuted.length; j++) {
                const permutedArray = [currentNum].concat(remainingNumsPermuted[j]);
                
                result.push(permutedArray);
                }
            }
            return result;
        }

        console.log(permute([1,2,3]))
