I didn't make a list, but let me give an example. Page 22 where variable declarations are introduced:
If a variable is declared and not given an initial value then great care must be taken not to use the undefined value of the variable until one has been properly given to it. If a program does use the undefined value in an uninitialised variable, its behaviour will be unpredictable; the program is said to be erronous.
