Remove object in array by key

I'm trying to remove object by key in JavaScript

here is example of array

{
Account Manager: {selected: true}
Arrival: {selected: true}
Client: {selected: true}
Client Contact: {selected: true}
Created: {selected: true}
Created by: {selected: true}
Departure: {selected: true}
Destination: {selected: true}
Keywords: {selected: true}
Status: {selected: true}
}

now i'm trying to remove status and client from this array but i don't know how to make it. I've tried with this:

for(var i=0; i<list.length; i++) {
    if(list[i] == 'Status' || list[i] == 'Client') {
       list.splice(i, 1);
    }
}

We can use delete keywaord for that -:

delete object["keyName"];

This will remove that specific key...

The provided sample is an Object and not an array. Since you're using AngularJS you can directly use JavaScript to remove the key from the object.

Below is a sample by simply using the delete() method

 const _object = {
      "Account Manager": { selected: true },
      "Arrival": { selected: true },
      "Client": { selected: true },
      "Client Contact": { selected: true },
      "Created": { selected: true },
      "Created by": { selected: true },
      "Departure": { selected: true },
      "Destination": { selected: true },
      "Keywords": { selected: true },
      "Status": { selected: true }
    }

    delete _object["Status"];

    console.log(_object);

We can use reduce function for that -: 

let newList = Object.keys(oldList).reduce((acc, key) => {
    if(key !== 'Status' || key !== 'Client'){
        acc[key] = oldList[key]
    }
    return acc;
}, {})
