I have an array of objects
let people = [{
Name: 'Bob',
Age: '45',
},
{
Name: 'Jim',
Age: '45',
}
];
let person = people.filter(person => person.Name=== 'Bob')
This returns Bob but how do I delete him?
This only seems to delete a property
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete
so it seems I need an index or maybe there is a better ES6 way?
You can use splice and findIndex methods and remove specific object from an array.
let people = [{"Name":"Bob","Age":"45"},{"Name":"Jim","Age":"45"}]
people.splice(people.findIndex(({Name}) => Name == "Bob"), 1);
console.log(people)
people.splice(people.findIndex((foo) => foo.Name == "Bob"), 1); console.log(people)To remove bob simply do the opposite equality check
let person = people.filter(person => person.Name !== 'Bob')
To mutate the original array, you can use splice
const index = people.findIndex(person => person.Name === 'Bob');
if (index > -1) {
people.splice(index, 1);
}
people = people.filter(person => person.Name !== 'Bob') ;name = "Bob"splice()people.splice(people.findIndex(({Name}) => Name == "Bob"), 1);
Just simply change your code in the filter section from "===" to "!==" to delete it.
let people = [
{
Name: "Bob",
Age: "45",
},
{
Name: "Jim",
Age: "45",
},
];
let person = people.filter((person) => person.Name !== "Bob");
console.log(person);
splice()??let person = people.filter(person => person.Name!== 'Bob'). Filter will only return elements that return false to your condition and ignore the others.
