Does anybody can help me how to retrieve array/object values using High Order Functions?
this is my data, the block repeats several times and I need to retrieve the resident names.
species: [
{
id: lionId,
name: 'lions',
popularity: 4,
location: 'NE',
availability: ['Tuesday', 'Thursday', 'Saturday', 'Sunday'],
residents: [
{
name: 'Zena',
sex: 'female',
age: 12,
},
etc
I have tried the following code, but only can get the residents group, and I need to extract only residents names.
return species.map((e) => e.residents);
Your map method will return an array of arrays with resident objects inside of it. Use flatMap to flatten the data to a single array of resident objects.
Then map over the resident objects and return the name property for each resident. This will give you an array of resident names.
const species = [{
id: '',
name: 'lions',
popularity: 4,
location: 'NE',
availability: ['Tuesday', 'Thursday', 'Saturday', 'Sunday'],
residents: [{
name: 'Zena',
sex: 'female',
age: 12,
}, ],
}];
const residents = species.flatMap(specie => specie.residents);
const residentNames = residents.map(resident => resident.name);
console.log(residentNames);
