Quiero ordenar a los asistentes según los groups clave, que es una matriz de grupos (función como etiquetas). Quiero ordenar por el orden de clasificación predefinido y luego por si sortOrder es verdadero si existen varios asistentes para el mismo grupo. Pero estoy realmente atascado con la forma de verificar si existe un nombre de grupos y luego clasificarlos de manera eficiente por el orden predefinido.
const attendees = [ { name: "Peter", groups: [{ name: "agency", main_contact: false, stand_in_contact: true }], }, { name: "Alex", groups: [{ name: "agency", main_contact: true, stand_in_contact: false }], }, { name: "Nina", groups: [ { name: "production", main_contact: true, stand_in_contact: false }, ], }, { name: "Christina", groups: [ { name: "client", main_contact: true, stand_in_contact: false }, { name: "crew", main_contact: false, stand_in_contact: false }, ], }, ]; const sortAttendees = (attendees) => { const sortOrder = ["agency", "client", "production", "crew"]; // return sortOrder.indexOf(a.type) - sortOrder.indexOf(b.type); if (!attendees || attendees.length == 0) return []; return attendees.sort((a, b) => { if (a.groups.some((group) => group.name === "agency")) { return -1; } if (a.groups.some((group) => group.name === "client")) { return 1; } if (a.groups.some((group) => group.name === "production")) { return 1; } return 1; }); };Resultado
const attendees = [ { name: "Alex", groups: [{ name: "agency", main_contact: true, stand_in_contact: false }], }, { name: "Peter", groups: [{ name: "agency", main_contact: false, stand_in_contact: true }], }, { name: "Christina", groups: [ { name: "client", main_contact: true, stand_in_contact: false }, { name: "crew", main_contact: false, stand_in_contact: false }, ], }, { name: "Nina", groups: [ { name: "production", main_contact: true, stand_in_contact: false }, ], }, ];Parece que los grupos deben ordenarse primero, luego puede ordenar a los asistentes.
