    You can map() over the array and create new object were you keep one, and add a key from test[0] with value test[1].

    const what_i_have = [
  {
    "one":"1",
    "test":[
      "two",
      "2"
    ]
  }
];

const what_i_need = what_i_have.map(({ one, test }) => ({ one, [test[0]]: test[1] }));

console.log(what_i_need)

    You could check for the nested array and take the entries or the entries from the outer properties.

    const
    data = { one: "1", test: ["two", "2"] },
    result = Object.fromEntries(Object
        .entries(data)
        .map(([k, v]) => Array.isArray(v) ? v : [k, v])
    );

console.log(result);
