What types of errors get into try-catch statements in Javascript?

Question

If i write

try { null = foobar } catch(e) { alert( e ) };

does not warn anything, but is written to the console ReferenceError. Nonetheless,

try { barfoo = foobar } catch(e) { alert( e ) };

shows warning c ReferenceError.

So the question is: what types of errors in what context fall into try-catch statements?

Answer 1

So, your first line of code is invalid JavaScript syntax. This is why you get:
ReferenceError: Invalid left-hand side in assignment(You cannot assign vars to null)

The second line - this syntax, but throws:
ReferenceError: foobar is not defined.
