Dear all,

I have recently started using workflows and as every beginner I am flooded with questions.

I am not seeking for an essay type of answer but, just to give you an idea, of the type of questions I have when creating a flow:

What is:

the Question Mark I keep seeing in the advance mode e.g. in a condition block? I thought it was some sort of an operant or and evaluation character as in python but it doesn't seem so and I cannot find any information.
the @ symbol. Same question as the ? symbol above.
what is the Item (and items), Body, Value (list of items) e.t.c.
when in advance mode I see something like this
```
@not(equals(items('Apply_to_each')?['a'], items('Apply_to_each')?['b']))
```
what is the nomeclature for all the round and square brackets?
Am I right to say that all the formulas/code is in REST? And they have to be contained in a JSON schema?

Again, as I said I am not looking for an answer here (but if you are kind enough to answer some of these Qs it will be much appreciated) but more like links (and books) that will help me understand it better.

P.S. I have been trying all day to create a formula within a "Compose" action that will take only the first three elements of an input array and I still cannot make it.

Many thanks in advance.
