How to use re:replace

[ta7tUHIJHx4RwR21]

If I have a JSON watch that returns something like:

{
{
"StoreName":"ToysRUs"
"Inventory":"3333"
}
{
"StoreName":"EBgames"
"Inventory":"5555"
}
{
"StoreName":"KBtoys"
"Inventory":"4444"
}
}

If Inventory:3333 = in stock, 5555 = not available, and 4444 = on order, how do I replace the values with "in stock", "not available", or "on order"? So it would read:

{
{
"StoreName":"ToysRUs"
"Inventory":"in stock"
}
{
"StoreName":"EBgames"
"Inventory":"not available"
}
{
"StoreName":"KBtoys"
"Inventory":"on order"
}
}

I figured it out using a jq if then statement.
if .Inventory == "3333" then "in stock" elif .Inventory == "5555" then "not available" elif .Inventory == "4444" then "on order" else "unknown" end
