Adding effect to an item via JSON

[DirtEngineer]

I am generating items from a JSON file. I want to add one or more effects to some of them, like a potion. 
What is the format for the JSON element that would do that? As in <"blah": "minecraft.effect.whatever_effect">

mob effects (potion effects) apply to entities, you don't apply them to items.

you can add enchantments using the enchant_with_levels loot item function

if you want examples just look at the loot tables in the minecraft jar

I was able to do it by adding a new array to the JSON entries and adding the effects when I build them for registration.
<,
"effect":
[
     { "location": "minecraft:nausea", "duration": "600", "amplifier": 2 },
     { "location": "minecraft:slowness", "duration": "600", "amplifier": 0 },
     { "location": "minecraft:weakness", "duration": "600", "amplifier": 0 }
]>
