 Not ending statements with semicolons.
 Not inserting commas as required in functions parameter lists.
 Leaving out an ASCII space character between characters forming a
different legalbut unwantedoperator.
 Confusing similar-looking operators such as && with &, == with =, //
with /, etc.
 Inadvertently inserting ASCII nonprinting characters into a source-
code file.
