const outputKeys = ['name', 'capital', 'region', 'languages', 'flag'];
const output = ent.map(item =>
outputKeys.reduce((val, key) => ({ ...val, [key]: item[key] }), {})
);
console.log(output);

experted the value to be language: [{},{},{}];
i have tried to do like this:
const outputKeys = ['name', 'capital', 'region', 'languages', 'flag'];
const output = ent.map(item => outputKeys.reduce((val, key) => ({ ...val, [key]: item[key].flat(infinity) }), {}) ); console.log(output);
look out the first object the language consist the nested arrays ! thanks in advance .
