Why && lightning expression operator doesn't work?
Clash Royale CLAN TAG#URR8PPP
According to this reference the syntax below:
<aura:if isTrue="!and(v.isVisible,!empty(v.subjectsList))">
should be equivalent to:
<aura:if isTrue="!v.isVisible && !empty(v.subjectsList)">
However, I receive the message below when I try to save the lightning component to the sandbox:
FIELD_INTEGRITY_EXCEPTION - c:SubjectSelectionView_GCC:69,34: ParseError at [row,col]:[70,34]
Message: The entity name must immediately follow the '&' in the entity reference.: Source
So, What am I missing?

Instead of &&
you can use &&
(the HTML entity for &). That seems to satisfy the parser and the expression will still execute your logic correctly.
So your code will be:
<aura:if isTrue="!v.isVisible && !empty(v.subjectsList)">
Edit
As noted in the comments, it's probably better to use and
like:
<aura:if isTrue="!and(v.isVisible, !empty(v.subjectsList))">

@JayantDas No, Lightning requires it. It is not specific to the Developer Console. Go ahead and try it out in your favorite IDE. ... It's technically an oversight in the documentation, as far as I can tell. Aura has always worked this way.

AND function is more readable in case we have 2 parameters:<aura:if isTrue="!and(v.isVisible, !empty(v.subjectsList))">
