React is not iterable

var obj = { 'France': 'Paris', 'England': 'London' };
// Iterate over the property names:
for (let country of Object.keys(obj)) {
    var capital = obj[country];
    console.log(country, capital);
}

for (const [country, capital] of Object.entries(obj))
    console.log(country, capital);
