Select all correct statements about val form and def form definitions:

Get an explanation when it's available:

The difference between val and def becomes apparent when the right hand side does not terminate.
Given
```
def loop: Boolean = loop
```
A definition
```
def x = loop
```
is OK, but a definition
```
val x = loop
```
will lead to an infinite loop.
Function parameters can be passed by value or be passed by name.
The same distinction applies to definitions.
The def form is “by-name”, its right hand side is evaluated on each use.
There is also a val form, which is “by-value”.
Example:
```
val x = 2
val y = square(x)
```
The right-hand side of a val definition is evaluated at the point of the definition itself.
Afterwards, the name refers to the value. For instance, y above refers to 4, not square(2).
