JavaScript join between objects

Question

I have JSON object that has some values, and from those values, I need to generate a name, basically, I need to add '/' between those values. So my object looks like this

"options":[
            {
               "value":"Red",
               "key":"Color"
            },
            {
               "value":"L",
               "key":"Size"
            }
         ]
 

And for this specific case I did it like this:

title: `${combination[0].value}/${combination[1].value}`

And the output looks like Red/L, and this is correct. But what If I have more or less objects?

What would be the easiest way to make this work?
