JavaScript How to delete elements from array?

Let we have an array of objects.
Some objects should be deleted from the array.
Let these objects be marked with ban property.
OK.
Let’s define the removeBanned function.
The function has one parameter: an array to delete items.
For every item of the array we check the ban property.
And if this property is set to true we use the splice method
to remove the element from the array.
Else we move to the next item.
Let’s remove banned from the array.
The banned items have been deleted from the array.
