could you help with these problem.
I need to filter the items in the array that contains certains activities in their object array. Heres is the code:
let userArray = [{
name: "alonso",
age:16,
hobbies: [{activity:"videogames", id: 1}, {activity:"watch tv", id:2}]
},
{
name: "aaron",
age:19,
hobbies: [{activity:"videogames", id:1}, {activity:"soccer", id:8}]
},
{
name: "Luis",
age:27,
hobbies: [{activity:"code", id:3}, {activity:"soccer", id:8}]
}]
if "videogames" is passed by string the output expected is:
[{
name: "alonso",
age:16,
hobbies: [{activity:"videogames", id: 1}, {activity:"watch tv", id:2}]
},
{
name: "aaron",
age:19,
hobbies: [{activity:"videogames", id:1}, {activity:"soccer", id:8}]
}]
You can use Array.prototype.filter() combined with Array.prototype.some():
const userArray = [{name: 'alonso',age: 16,hobbies: [{ activity: 'videogames', id: 1 },{ activity: 'watch tv', id: 2 },],},{name: 'aaron',age: 19,hobbies: [{ activity: 'videogames', id: 1 },{ activity: 'soccer', id: 8 },],},{name: 'Luis',age: 27,hobbies: [{ activity: 'code', id: 3 },{ activity: 'soccer', id: 8 },],},]
const getUsersByActivity = (array, activity) => array.filter(
user => user.hobbies.some(hobby => activity === hobby.activity)
)
const result = getUsersByActivity(userArray, 'videogames')
console.log(result)var users = [
{
name: "aaron",
age: 19,
hobbies: [
{ activity: "videogames", id: 1 },
{ activity: "soccer", id: 8 },
],
},
{
name: "Luis",
age: 27,
hobbies: [
{ activity: "code", id: 3 },
{ activity: "soccer", id: 8 },
],
},
];
function getUsersBasedOnActivity(activity) {
return users.filter((data) => {
const hobbies = data.hobbies.map((hobby) => hobby.activity);
return hobbies.includes(activity);
});
}
console.log(getUsersBasedOnActivity('videogames'))
using array.filter you could filter out the objects that dont have the trait you are looking for userArray.filter(x => x.hobbies[0].activity === "videogames");
