This is a JSON snip that is created in WooCommerce by a plugin that adds some metadata. I cannot change the formatting of this JSON because it is generated by a plugin. The problem is that the keys and the values are added in a weird way. I am iterating through the line_items and statically referencing this data which I don't want to do, I would like to know if there is a smart way to reference for example: "key": "_cpo_product_id", "value": "3572", if this was formatted correctly it would be: "_cpo_product_id": "3572" and not have "value" as a key, and it would be accessed by: foo.line_items[i]._cpo_product_id but with this configuration I am a bit lost, I am sure there is an easy way to find the value for a specific key. I am doing this on Google app scripts, but a solution in JavaScript should suffice.
