The methods which do not mutate the original array but always return a new array are called non-mutation methods. Below are the list of non-mutation methods,

filter()

concat()

slice()

For example, lets take a todo list where it replaces the old array with new one based on status filter,

vm.todos = vm.todos.filter(function (todo) {

  return todo.status.match(/Completed/)

})

This approach won't re-render the entire list due to VueJS implementation.
