So let say we have a JSON object like so:
{
"blacksmith": {
"sword": {
"name": "Altar of skies",
"description": "A really powerful sword",
"rarity": 5
},
"bow": {
"name": "Hell's string",
"description": "A really powerful bow",
"rarity": 4
},
"spear": {
"name": "Heart piercer",
"description": "A really powerful spear",
"rarity": 5
}
},
"merchant": {
"sword": {
"name": "Wind's wand",
"description": "A really powerful sword",
"rarity": 5
},
"bow": {
"name": "Heaven's string",
"description": "A really powerful bow",
"rarity": 4
},
"spear": {
"name": "Digger",
"description": "A really powerful spear",
"rarity": 5
}
}
}
And the user gives me a string, If the string is "blacksmith" or "merchant" I want to return all the stuff they sell but if it's only a specific weapon name like "Altar of skies" it'd return only that weapon's information.
For example:
User string: "merchant"
Returns:
"merchant": {
"sword": {
"name": "Wind's wand",
"description": "A really powerful sword",
"rarity": 5
},
"bow": {
"name": "Heaven's string",
"description": "A really powerful bow",
"rarity": 4
},
"spear": {
"name": "Digger",
"description": "A really powerful spear",
"rarity": 5
}
}
User string: "Altar of skies"
Returns:
{
"name": "Altar of skies",
"description": "A really powerful sword",
"rarity": 5
}
let d = { "blacksmith": { "sword": { "name": "Altar of skies", "description": "A really powerful sword", "rarity": 5 }, "bow": { "name": "Hell's string", "description": "A really powerful bow", "rarity": 4 }, "spear": { "name": "Heart piercer", "description": "A really powerful spear", "rarity": 5 } }, "merchant": { "sword": { "name": "Wind's wand", "description": "A really powerful sword", "rarity": 5 }, "bow": { "name": "Heaven's string", "description": "A really powerful bow", "rarity": 4 }, "spear": { "name": "Digger", "description": "A really powerful spear", "rarity": 5 } } }

)Using Object.keys and Array.includes to match with top-level keys
Uisng Object.values() to extract values out of top level objects, flatMap to flat all objects inside top level objects, and find in the flattern objects
