Adding values to existing key in object Javascript

How do I add more names to an age group in object with simple javascript? Not using any built in function like reduce(), append(), assign() etc. Please let me know my mistakes and what I am missing. Any help is appreciated :)

My output is { '10': [ 'Victoria' ], '12': [ 'Samantha' ] } My second 'if' statement never executed

Expected Output:

{  "12": ["Kathy", "Krystal", "Samantha"],  "10": ["Victoria"]  }  

const ageGroup = function(girls) {        let people = {};        for(let i = 0; i < girls.length; i++){      if(girls[i].age !== people.age){        people[girls[i].age] = [girls[i].name];        }      if(girls[i].age === people.age){        people.push([girls[i].name]);      }        }    return people;    };    console.log(ageGroup([    {name: "Kathy", age: 12},    {name: "Victoria", age: 10},    {name: "Krystal", age: 12},    {name: "Samantha", age: 12}  ]));
