I am seeking a refined solution to create a function that retrieves the names of legal drivers from a given array of people:
function getNamesOfLegalDrivers(people) {
}
const driverArray = [
{ name: 'John', age: 14 },
{ name: 'Joey', age: 16 },
{ name: 'Jane', age: 18 }
];
console.log(getNamesOfLegalDrivers(driverArray), '<-- should output names of individuals over 16 years old, like ["Joey", "Jane"]');
If you're searching for methods on the Array prototype, consider using filter and map.
JavaScript
function listNamesOfEligibleDrivers(people) {
return people
.filter(function(person) { return person.age >= 16; })
.map(function(person) { return person.name; });
}
Explanation from MDN
filter() method creates a new array with elements that meet the criteria specified by the given function.map() method generates a new array by applying a function to each element of the original array.function retrieveLegalDriverNames(people) {
return people
.filter(person=>person.age >= 16) //obtain an array of person objects aged 16 and older
.map(person=>person.name) //extract names of individuals in the filtered array
}
One way to achieve this is by implementing the following function:
function retrieveLegalDriverNames(personnel)
{
var legalDriverNames = [];
for (var index in personnel) {
if(personnel[index].age >= 16){
legalDriverNames.push(personnel[index].name);
}
}
return legalDriverNames;
}
const samplePersonnelArray = [
{ name: 'John', age: 14 },
{ name: 'Joey', age: 16 },
{ name: 'Jane', age: 18 }
];
console.log(retrieveLegalDriverNames(samplePersonnelArray));
