Question

this code works perfectly on my browser but when i applied it on react native i have an error of

" Possible Unhandled Promise Rejection (id: 0): TypeError: obj.room_type_id.includes is not a function. (In 'obj.room_type_id.includes(id)', 'obj.room_type_id.includes' is undefined) "

 var data = [{ "floor": "1st", "name": "NAME0", "room_type_id": ["Y", "B", "S", "N"], "status": "Available" }, { "floor": "7", "name": "NAME54", "room_type_id": ["O", "G", "C", "S"], "status": "Available" }, { "floor": "64", "name": "NAME2", "room_type_id": ["A", "S", "Q", "D"], "status": "Available" }, { "floor": "Bddh", "name": "NAME3", "room_type_id": ["A", "X", "S", "D"], "status": "Available" }, { "floor": "Vh", "name": "NAME1", "room_type_id": ["A", "B", "C", "D"], "status": "Available" }, { "floor": "Dyd", "name": "NAME2", "room_type_id": ["A", "B", "C", "D"], "status": "Available" }] let id = "B"; let dataResult = data.filter((obj) => obj.room_type_id.includes(id)).length; console.log(dataResult)

Answer 1

Have a try by parsing the array object to the JSON object to use the array itteration methods.

let JSONData = JSON.parse(JSON.stringify(data))
let dataResult = JSONData.filter((obj) => obj.room_type_id.includes(id)).length;
