Estoy tratando de agregar una nueva entrada a una matriz después de que una determinada propiedad, en mi caso, "lugar", cambie. Sin embargo, tengo grandes problemas para encontrar un enfoque adecuado, porque la operación depende del siguiente objeto de la matriz.

 const initalData = [ { storyID: 1, place: 12, type: "Story" }, { storyID: 5, place: 12, type: "Story" }, { storyID: 99, place: 45, type: "Story" }, { storyID: 8, place: 31, type: "Story" }, { storyID: 16, place: 31, type: "Story" }, { storyID: 20, place: 45, type: "Story" }, { storyID: 22, place: 45, type: "Story" }, ];

 const targetData = [ { placeID: 12, type: "Place" }, // new added entry based on the next "place" { storyID: 1, place: 12, type: "Story" }, { storyID: 5, place: 12, type: "Story" }, { placeID: 45, type: "Place" }, // // new added entry based on the next "place" { storyID: 99, place: 45, type: "Story" }, { placeID: 31, type: "Place" }, // new added entry based on the next "place" { storyID: 8, place: 31, type: "Story" }, { storyID: 16, place: 31, type: "Story" }, { placeID: 45, type: "Place" },// new added entry based on the next "place" { storyID: 20, place: 45, type: "Story" }, { storyID: 22, place: 45, type: "Story" }, ];

Actualmente he mirado groupBy("place") como un posible enfoque, pero la estructura de matriz final aquí no es lo que necesito.
