I would recommend a method that takes the object and prints each with a defined space. Recursive call would add x amount of spaces each time you would go in deeper within the objects.

After the first time the php script tries accessing the CSS file, the server returns a status code 304. The easiest implementation to check for this would be the following:

What is a practical application of using an immutable type in a thread-safe way that differs from using a mutable type in the same way?

As noted in the comments, it's all about the variables.

If you have multiple threads accessing the same variable, then yes, you have to protect the variable in some way (lock, Interlocked, etc).

The benefit of immutable types comes in when you pass that data to another thread - creating another variable. All you need to do is copy the reference from one variable to another, and now the first variable can change however much it wants; the second variable remains immutable.

I think it's a bit easier to understand with an example like ImmutableStack. Let's say there's a "main" thread that pushes and pops that ImmutableStack; since this is immutable, each push/pop updates its own variable. If our "main" thread wants to give another thread a snapshot, it just copies its current variable to another variable for that thread. Then the "main" thread can continue pushing/popping/updating its own variable with impunity. The "secondary" thread has its own immutable snapshot.

In a more general situation, this can be useful with one or more readers/responders, where each "read" loop starts with capturing the current state of the shared variable and using that local copy for the duration of the loop.

If you wanted to snapshot a mutable value, that would require doing a deep clone. Imagine if string was mutable, like it is in other languages. In that case, copying the value (reference) of the string would be insufficient; one thread could change a single character while another thread was trying to do something else with the value. In order to capture a true snapshot of a mutable string value, you'd have to copy the entire string to a new string.

There are other benefits to immutable types in general (design, etc), but this "reference snapshot" benefit is one that specifically benefits multithreading.

To not assign changes to props.item.title, do:

• Remove the .sync in .
• Replace v-model with :value in .

As .sync has an implicit @return-value:update="props.item.title = $event" and v-model has an implicit @input="props.item.title = $event (roughly), the above alone (removing .sync and replacing v-model with :value) would stop title from being directly modified.

To make it being modified via dispatch also add an @input listener that calls the dispatch: @input="onUpdateCourse({ id: props.item.id, title: props.item.title})".

Finally, here's how your code should look like:

Here's how you can achieve this conceptually:

The constraints on the extension are separated by a comma, not by &. The containsTheSameElements must take a [T] argument where T is a RawRepresentable with the same RawValue as the array elements.
