Combining Arrays of Javascript Objects with Different Data Types

I have two arrays of objects which I need to combine in a specific way. You can view the arrays here: https://plnkr.co/edit/RQs9WWs1hcxmuKGIgEhM?p=preview

My goal is to merge these arrays so that any elements missing from one array are added to create a complete set. For example, if an element exists only in the first array, it should be included in the final combined array.

Here is the desired output:

[{"car":"A","miles":100},{"car":"B","miles":100},{"car":"C","miles":100,"sold":"Y"}]

[{"car":"B","miles":100,"sold":"Y"},{"car":"C","miles":100,"sold":"Y"}]

[{"car":"A","miles":100},{"car":"B","miles":100,"sold":"Y"},{"car":"C","miles":100,"sold":"Y"}]

It seems Angular's merge method will not work for this scenario because the objects do not match up perfectly. I am considering looping over the arrays and creating a common list by generating unique identifiers for each object to assist in matching them.

Embracing the Lodash library (or underscore) can greatly simplify your tasks, offering seamless integration with Angular for added convenience.

To accomplish your goal using Lodash, consider implementing the following code snippet:

_.values(_.extend(_.keyBy(x, 'vehicle'), _.keyBy(y, 'vehicle')));
