Docs about comparison operators saying case-sensitive

Question

_{Above all sorry about the title, couldn't find a good one. Please edit if you think of any}

I stumbled upon this description about equals operator in Salesforce docs.

OPERATOR    NAME    DESCRIPTION
  ==       Equals   ... String comparisons that use the equals operator are case-sensitive

But in Developer Console I get the result as below.

'foo' == 'Foo' 
>>> True

My question is, am I missing something here?

That documentation is about Einstein Analytics, which has different semantics from other areas of Salesforce.

In Apex, the == operator is case-insensitive:

String comparison using == is case-insensitive.

Case-sensitive String comparison in Apex is done using String.equals(). Note also there's a few places where Apex does do case-sensitive String matching; List.contains() and Set.contains() are among them.
