Map object inside array in javascript?

Question

This is my array:

const array = [
    {
        "fare": "399.00",
        "passenger": {
            "age": "21",
            "gender": "MALE",
            "name": "Test1"
        },
    },
    {
        "fare": "399.00",
        "passenger": {
            "age": "21",
            "gender": "FEMALE",
            "name": "Test2"
        },
    }
]

How to map the object inside the array, and how to convert the object to the required output

Required output:

Test1(M), Test2(F)

Above contains "name" and gender - if its male then just "M" and if its female just "F"

As of now i tried,

array.map(o => ({ name: o.passenger.name, gender: o.passenger.gender })))

But how to convert this as expected output !

Like this

const array = [{ "fare": "399.00", "passenger": { "age": "21", "gender": "MALE", "name": "Test1" }, }, { "fare": "399.00", "passenger": { "age": "21", "gender": "FEMALE", "name": "Test2" }, } ];

const output = array
  .map(({passenger}) => `${passenger.name}(${passenger.gender.slice(0,1)})`)
  .join(", ")

console.log(output);
