I have a JSON I would like to re-arrange my data, so that I can group all items by category name. Here is my data.
[
{
"id":317,
"name":"Ingram's Camphor Cream",
"slug":null,
"product_category_id":15,
"industry_id":2,
"deleted_at":null,
"category":{
"id":15,
"name":"Skincare",
"slug":null,
"industry_id":2,
"deleted_at":null,
"sku_id":3,
"is_active":1
},
},
{
"id":323,
"name":"Zimgold",
"slug":null,
"product_category_id":2,
"industry_id":2,
"category":{
"id":2,
"name":"Cooking Oils",
"slug":null,
"industry_id":2,
"sku_id":2,
"is_active":1
}
}
]
I would like to have a result like so:
[
'Skincare': [ {}],
'Cooking Oils': [{}]
]
Thank you in advance. I would really appreciate your help.
You can reduce the array of products to a map of names to product arrays with a reducer like this:
const grouped = products.reduce((grouped, product) => {
const key = product.category.name
// replace the array at [key] with a new one including the current element
return { ...grouped, [key]: (grouped[key]??[]).concat(product)}
}, {})
Maybe there is a a prettier way but something like this would work
var groupedData = {};
data.forEach(item => {
if (!groupedData[item.category.name]) {
groupedData[item.category.name] = [];
}
groupedData[item.category.name].push(item);
})
arr.map(item=>{
let key = item.category.name
return {[key]:item}
})
