'separate json object into different index
I have following array which consist of json objects:
items = [
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-10',
creditAmount: '200',
numberBank: '12345',
},
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-14',
creditAmount: '159',
numberBank: '12345',
},
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-15',
creditAmount: '3421',
numberBank: '12345',
},
{
id: '2',
name: 'George',
transactionDate: '2012-09-15',
creditAmount: '6000',
numberBank: '13345',
},
{
id: '2',
name: 'George',
transactionDate: '2012-09-16',
creditAmount: '6565',
numberBank: '13345',
}
]
I want to separate the array index for each same id
as an example :
[
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-10',
creditAmount: '200',
numberBank: '12345',
},
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-14',
creditAmount: '159',
numberBank: '12345',
},
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-15',
creditAmount: '3421',
numberBank: '12345',
}
],
[
{
id: '2',
name: 'George',
transactionDate: '2012-09-15',
creditAmount: '6000',
numberBank: '13345',
},
{
id: '2',
name: 'George',
transactionDate: '2012-09-16',
creditAmount: '6565',
numberBank: '13345',
}
]
How to do like that ? thanks
Solution 1:[1]
you can use reduce to group by id and then the values of the resultant using Object.values
let items = [
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-10',
creditAmount: '200',
numberBank: '12345',
},
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-14',
creditAmount: '159',
numberBank: '12345',
},
{
id: '1',
name: 'Josh',
transactionDate: '2012-08-15',
creditAmount: '3421',
numberBank: '12345',
},
{
id: '2',
name: 'George',
transactionDate: '2012-09-15',
creditAmount: '6000',
numberBank: '13345',
},
{
id: '2',
name: 'George',
transactionDate: '2012-09-16',
creditAmount: '6565',
numberBank: '13345',
}
]
let res = Object.values(items.reduce((acc,curr)=> {
if(!acc[curr.id])acc[curr.id]=[]
acc[curr.id].push(curr)
return acc
},{}))
console.log(res)
