Renvoie le premier objet à contenir une valeur spécifique dans un tableau d'objets imbriqués à niveaux multiples javascript

J'ai un objet qui contient des tâches imbriquées et groupées par jour de la semaine. Je ne peux pas changer sa structure. Quelle est la manière optimale de retourner la première tâche à partir de celle où la valeur de la clé "status" de cette tâche! == "complete".Renvoie le premier objet à contenir une valeur spécifique dans un tableau d'objets imbriqués à niveaux multiples javascript

Une légère amélioration par rapport à la réponse de Abhishek Soni. Plutôt que de filtrer toutes les tâches complètes, nous pouvons utiliser .find pour renvoyer le premier élément du tableau qui renvoie true.

const firstCompletedTasked = response.tasks[0].tasks.find(task => task.status === 'complete');

Si intérêt pourriez-vous s'il vous plaît expliquer pourquoi c'est une amélioration? La vitesse? – larpo

La vitesse est un petit facteur, car find retournera dès qu'il trouvera une correspondance, alors que le filtre traitera tout le tableau. La grande chose pour moi est que find va retourner l'objet, pas un tableau. –

En supposant que vous enregistrez cet objet dans une variable nommée response:

let firstInCompleteTask = response.tasks[0].tasks.filter((task)=>{ 
    return task.status !== 'complete' 
})[0];

En outre, le premier tasks tableau a deux objets, qui ont alors un tableau de tâches en eux. Le code ci-dessus renvoie la première tâche incomplète du premier objet.

Si vous voulez des tâches incomplètes à la fois des objets, vous devez utiliser quelque chose comme:

let incompleteTasks = []; 
for(i = 0; i < response.tasks.length; i++){ 
    let firstInCompleteTask = response.tasks[i].tasks.filter((task)=>{ 
     return task.status !== 'complete' 
    })[0]; 

    incompleteTasks.push(fistInCompleteTask); 
}
