What are the array detection non-mutation methods?

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,

1. filter()
2. concat()
3. slice()
4. map()
5. reduce()
6. find()
7. includes()
8. every()
9. some()
10. indexOf()
11. join()

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.
