Necesito fusionar una matriz de entregas que tienen notas, ¿cómo eliminaría el objeto duplicado pero mantendría la cadena de notas y la almacenaría en una matriz para el objeto no duplicado?
Clave comienza el número de entrega:
"data": [ { "deliveryNumber": "0000001", "deliveryDate": "2021-10-01T00:00:00.000Z", "dateBeginProcess": null, "dateFinishedProcess": null, "status": "", "notes": "Note 1" }, { "deliveryNumber": "0000001", "deliveryDate": "2021-10-01T00:00:00.000Z", "dateBeginProcess": null, "dateFinishedProcess": null, "status": "Ready", "notes": "Note 2" }, { "deliveryNumber": "0000002", "deliveryDate": "2021-10-01T14:21:00.000Z", "dateBeginProcess": null, "dateFinishedProcess": null, "status": "Ready", "notes": null } ]dentro
"data": [ { "deliveryNumber": "0000001", "deliveryDate": "2021-10-01T00:00:00.000Z", "dateBeginProcess": null, "dateFinishedProcess": null, "status": "Ready", "notes": ["Note 1", "Note 2"] }, { "deliveryNumber": "0000002", "deliveryDate": "2021-10-01T14:21:00.000Z", "dateBeginProcess": null, "dateFinishedProcess": null, "status": "Ready", "notes": null } ]Puede usar Array.prototype.forEach() para recorrer la matriz de notas. Si se encuentra una nota dos veces, sume sus notas.
const notes = [ { "deliveryNumber": "0000001", "deliveryDate": "2021-10-01T00:00:00.000Z", "dateBeginProcess": null, "dateFinishedProcess": null, "status": "", "notes": "Note 1" }, { "deliveryNumber": "0000001", "deliveryDate": "2021-10-01T00:00:00.000Z", "dateBeginProcess": null, "dateFinishedProcess": null, "status": "Ready", "notes": "Note 2" }, { "deliveryNumber": "0000002", "deliveryDate": "2021-10-01T14:21:00.000Z", "dateBeginProcess": null, "dateFinishedProcess": null, "status": "Ready", "notes": null } ] let filteredArray = [] notes.forEach(note => { let noteFound = filteredArray.find(el => el.deliveryNumber === note.deliveryNumber) if(noteFound){ // not first encounter // add notes together noteFound.notes.push(note.notes) }else{ // first encounter // make notes an array note.notes = [note.notes||''] filteredArray.push(note) } }) console.log(filteredArray)
