how to filter and add conditional statements of the data coming from json local file in react native using map

the thing is i have a json file and a need to know how to filter my data result depending on the city that i want to show. i have already tried working with filter like this:

  agadir_medicineList() {

    return this.state.data.filter(data.city === "Agadir").map(medicine => (
      <Medicine_list key={medicine.title} medicine={medicine}  />
    ));

but it didn't work. this is my json file data:

]
{
    title: "Dr. kareem",
    city: "Inezgane",
    speciality: "Généraliste",
    tel: "tel:000000000",
},
{
    title: "Dr. Ahmed",
    city: "Agadir",
    speciality: "Généraliste",
    tel: "tel:000000000",
},
{
    title: "Dr. Jack",
    city: "Ait Melloul",
    speciality: "Généraliste",
    tel: "tel:000000000",
}
]

You were close! The filter method expects a callback function as first parameter. Your code should look like:

agadir_medicineList() {
    return this.state.data.filter(data => data.city === "Agadir").map(medicine => (
      <Medicine_list key={medicine.title} medicine={medicine}  />
    ));
