arrayDatas.map(details => details.map(d => d.id))

Working example: 

const arrayDatas = [
  [{id:234, name: 'eric'},{id:235, name: 'thomas'},{id:236, name: 'louvin'}],
  [{id:230, name: 'jason'},{id:233, name: 'lois'},{id:238, name: 'serge'},{id:237, name: 'natasha'},{id:236, name: 'berthe'}]
];

console.log(arrayDatas.map(details => details.map(d => d.id)))

Or you can also do it with nested for loop:

    const arrayDatas = [
      [{id:234, name: 'eric'},{id:235, name: 'thomas'},{id:236, name: 'louvin'}],
      [{id:230, name: 'jason'},{id:233, name: 'lois'},{id:238, name: 'serge'},{id:237, name: 'natasha'},{id:236, name: 'berthe'}]
    ];

    let result = [];
    for(let details of arrayDatas) {
        let currentDetails = []
        for(let d of details) {
            currentDetails.push(d.id);
        }
        result.push(currentDetails);
    }
    console.log(result);
