If function is true then do this

I’m trying to figure out how to make this work.

I want the validation function to check if all the user inputs are true, then a message in success ID will show You have successfully created an account. once the submit button is clicked.

How can I make this work?

How to get list with of property from array of objects unless it contains another item with certain value?

I have an array of objects, and I need to get list with certain property from that array of objects. But i need that list to contain only those values where object was containing another property with certain element.
This is very confusing so i made an example.
Let’s say i have an array with objects.

  employees = [
           {
            n: 'case 1',
            date: '2021-05-4',
            id: '123',
            user: [{name: 'Vlad', id: '1'}, {name: 'Misha', id: '2'}],
            isPresent : false,
           },
           {
            caseName: 'case 2',
            date: '2021-05-4',
            id: '124',
            user: [{name: 'Alina', id: '3'}, {name: 'Alex', id: '4'}],
            isPresent : false,
           },
           {
            caseName: 'case 3',
            date: '2021-05-4',
            id: '126',
            user: [],
            isPresent : true,
           },
        ]

And my task is to get a list of IDs from array of objects, but i need ID only from those objecrs which have isPresent as true.
So i need [‘123’, ‘124’].

I could use a loops and conditions and so on. But i wondering is it possible to do with one line ? Something like this:

employees.filter(item => { return item.isPresent === true }))

But i need only IDs not whole objects.

Same element is more than one time then it will return true otherwise it will be false

If the same element is more than one time then it will return true otherwise it will be false.
and push the return value data in output.

var array = [
  { id: 1, value: 10 },
  { id: 2, value: 10 },
  { id: 3, value: 10 },
  { id: 4, value: 56 },
  { id: 5, value: 56 }
]

Output will be like this

var output = [
  { id: 1, value: 10, matched: true },
  { id: 2, value: 10, matched: false },
  { id: 3, value: 10, matched: false },
  { id: 4, value: 56, matched: true },
  { id: 5, value: 56, matched: false }
]

how webRTC peerconnection totalAudioEnergy check

is importing entire module is Ok each time?

I am working on angular project and using firebase.

const timestamp = new Date().getTime()

await db.collection("admin_msg").insertOne({createdAt : timestamp , expiresIn : timestamp + 10000 });
await db.collection("admin_msg").createIndex({ expireAt: 1}, { expireAfterSeconds: 10 });

Try catch not working when using Axios Post Request

So what I expected from the code below was that when I get any errors in the request it would do a catch exception, but that is not happening, can anyone help me?

      try {

        const user = UsersServices.register({name: name, email: email, password: password})
        redirectToLogin(true)
      } catch (err) {
        setError(true)
      }

This is the POST I’m using

register: params => Api.post('users/register', params)
