I have an array which contains several arrays, each containing several objects, similar to this.
[[object1, object2],[object1],[object1,object2,object3]]
you can use flat() :
const data = [ [{id:1}, {id:2}], [{id:3}] ];
const result = data.flat();
console.log(result);
// you can specify the depth
const data2 = [ [ [ {id:1} ], {id:2}], [{id:3}] ];
const result2 = data2.flat(2);
console.log(result2);
in your case :
const data = [[{"_id":"55064111d06b96d974937a6f","title":"Generic Title","shortname":"generic-title","contents":"The Healing Center offers practical, social, and spiritual support to individuals and families. Services include, but are not limited to: food and clothing, job skills training and job search assistance, auto repair (Saturdays only), mentoring, financial counseling, tutoring, prayer, life skills training, and helpful information about local community services.
