How to combine four lists into one?

function combine(arr1, arr2, arr3, arr4) {
var result = [];
var maxLength = Math.max(arr1.length, arr2.length, arr3.length, arr4.length);

for (var i = 0; i < maxLength; i++) {
var val1 = arr1[i] !== undefined ? arr1[i] : "";
var val2 = arr2[i] !== undefined ? arr2[i] : "";
var val3 = arr3[i] !== undefined ? arr3[i] : "";
var val4 = arr4[i] !== undefined ? arr4[i] : "";

result.push(val1 + ":" + val2 + ":" + val3 + ":" + val4);
}

return result;
}

[[RES]] = combine([[ARR1]], [[ARR2]], [[ARR3]], [[ARR4]]);

JS

function combine(arr1, arr2, arr3, arr4) {

var result = [];

var maxLength = Math.max(arr1.length, arr2.length, arr3.length, arr4.length);



for (var i = 0; i < maxLength; i++) {

var val1 = arr1[i] !== undefined ? arr1[i] : "";

var val2 = arr2[i] !== undefined ? arr2[i] : "";

var val3 = arr3[i] !== undefined ? arr3[i] : "";

var val4 = arr4[i] !== undefined ? arr4[i] : "";



result.push(val1 + ":" + val2 + ":" + val3 + ":" + val4);

}



return result;

}



[[RES]] = combine([[ARR1]], [[ARR2]], [[ARR3]], [[ARR4]]);
