help you fix your problem I have 3 objects, each has a different length , Maybe something like this:
// Define max length
const maxLen = Math.max(obj1.length, obj2.length, obj3.length);

// Push missing itens for each arr object
obj1.push(...new Array(maxLen-obj1.length));
const arr = ... // your array of arrays
const maxLen = Math.max( ... arr.map(i => i.length));

arr.forEach( a => a.push(...new Array(maxLen-a.length));)
