Tengo la siguiente matriz que consiste en objetos json:
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', } ] Quiero separar el índice de matriz para cada mismo id
como ejemplo :
[ { 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', } ]¿Cómo hacer así? Gracias
puede usar reduce para agrupar por id y luego los valores del resultante usando Object.values
EDITAR
??= es la asignación lógica nula . El lado derecho se asignará siempre que el lado izquierdo sea null o undefined .
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', } ] const res = Object.values(items.reduce((acc,curr)=> { acc[curr.id]??=[] //similar to acc[curr.id] = acc[curr.id] || [] in this case acc[curr.id].push(curr) return acc },{})) console.log(res)
