I see that all the loops for objects returns the key as string and the value, but I want to operate on the keys of the object itself. If I have this object:
const data = {
person1: [
{ id: 1, name: Mike, age: 24 },
{ id: 2, name: Bob, age: 31 }
],
person2: [
{ id: 3, name: Christin, age: 21 },
{ id: 4, name: Michelle, age: 33 }
],
}
const removePersonById = (id) => {
// Check which person the id belongs to and remove that person
const persons = Object.keys(data).map(person => ...)
}
I wanted to loop through data and run .includes on each person in order to remove them by the id, but I am at a loss on how to do that.
You can loop through all keys and delete that the person you want by id using the filter() method
const removePersonById = (id) => {
var all = Object.keys(data);
for(let person of all){
data[person] = data[person].filter(a => a.id!=id);
}
}
Use Object.entries() so you can iterate over the keys and values together. Then you can test the value to see if the id is found.
Then use the delete operator to remove that key from the object.
const removePersonById = id => {
delete data[id];
};
const data = {
person1: [
{ id: 1, name: "Mike", age: 24 },
{ id: 2, name: "Bob", age: 31 }
],
person2: [
{ id: 3, name: "Christin", age: 21 },
{ id: 4, name: "Michelle", age: 33 }
],
};
const removePersonById = (id) =>
Object.entries(data).forEach(([key, value]) => {
if (value.some(({id: personid}) => personid == id)) {
delete data[key];
}
});
removePersonById(3);
console.log(data);let data = {
person1: [
{ id: 1, name: "Mike", age: 24 },
{ id: 2, name: "Bob", age: 31 }
],
person2: [
{ id: 3, name: "Christin", age: 21 },
{ id: 4, name: "Michelle", age: 33 }
],
}
const removePersonById = (id) => {
// Check which person the id belongs to and remove that person
data = Object.keys(data).reduce((acc,key) => {
if(data[key].some(person=>person.id===id)) return acc
acc[key]= data[key]
return acc
}, {})
console.log(`Remove person with ID ${id}: `,data)
}
removePersonById(1)
