THE SYNTAX OF A PROGRAMMING LANGUAGE tells you what code it is possible
to write—what the machine will understand. Style tells you what you ought to write—
what the humans reading the code will understand. Code written with a consistent, simple
style will be maintainable, robust, and contain fewer bugs. Code written with no regard to
style will contain more bugs. It may simply be thrown away and rewritten rather than
maintained.
