Copy array of objects and filter based on a property

Question

I have an array

Persons:[ 
{
Name: 'xz',
Job:'abc',
Manager:true},
{
Name: 'xy',
Job:'ac',
Manager:false},
{
Name: 'z',
Job:'a',
Manager:true}
]

I want to filter out the objects for which manager is true and set state i.e. Person_new:[] with this data using setState.

Can you help me out with this?

Is Person_New a new variable? or are you trying to replace the same state variable? — cullanrocks, May 21 '19 at 20:09
Person_new is An array? Are you trying to find one person or multiple? — cullanrocks, May 21 '19 at 20:10
Person_new is a different state and contains array of objects in the same way as Persons. I want to override the content of Person_new with that of Persons for which manager is true — RB19, May 21 '19 at 20:29

Because you have a boolean key in your array of objects, you can use filter to pick out only the Persons with manager set to true like so!

const managers = Persons.filter(person => person.Manager)

Use the Array filter method to identify the managers and then use the setState method:

const Persons = [
  { Name: 'xz', Job: 'abc', Manager: true },
  { Name: 'xy', Job: 'ac', Manager: false },
  { Name: 'z', Job: 'a', Manager: true }
];

const managers = Persons.filter(person => person.Manager);

this.setState({ persons: managers });

you mean like this? this.setState({Person_new: Persons}) – Simon Thiel May 21 '19 at 20:36
