like this, i have got 236 array of object but i want only few data from it like country, continent, total case, etc and stored it in usetate variable which will be array of object only but it will have this data only
let response = [
{
cases: { new: '+44', active: 216, critical: 1, recovered: 15364, 1M_pop: '35323', … }
continent: "Asia"
country: "Brunei"
day: "2022-01-10"
deaths: { new: null, 1M_pop: '221', total: 98 }
population: 443851
tests: { 1M_pop: '1562743', total: 693625 }
time: "2022-01-10T16:15:04+00:00"
},
{
cases: { new: '+2', active: 4, critical: null, recovered: 20, 1M_pop: '34', … }
continent: "Oceania"
country: "Solomon-Islands"
day: "2022-01-10"
deaths: { new: null, 1M_pop: null, total: null }
population: 711920
tests: { 1M_pop: '6321', total: 4500 }
time: "2022-01-10T16:15:04+00:00"
}
];
let mappedResponse = response.map(obj => {
const { country, continent } = obj;
return {
country,
continent
}
})
if I understand well you have an array with 236 entries. If that's right, here is what you can do:
const results = [
{
cases: {new: '+44', active: 216, critical: 1, recovered: 15364, 1M_pop: '35323', …}
continent: "Asia"
country: "Brunei"
day: "2022-01-10"
deaths: {new: null, 1M_pop: '221', total: 98}
population: 443851
tests: {1M_pop: '1562743', total: 693625}
time: "2022-01-10T16:15:04+00:00"
},
{
cases: {new: '+2', active: 4, critical: null, recovered: 20, 1M_pop: '34', …}
continent: "Oceania"
country: "Solomon-Islands"
day: "2022-01-10"
deaths: {new: null, 1M_pop: null, total: null}
population: 711920
tests: {1M_pop: '6321', total: 4500}
time: "2022-01-10T16:15:04+00:00"
}
];
const newArray = results.map(m => {
return { country: m.country, cases: m.cases }
})
