What are Preprocessors?

In computer science, a preprocessor is a program that processes its input data to produce output that is used as input to another program. The output is said to be a preprocessed form

of the input data, which is often used by some subsequent programs like compilers. The amount and kind of processing done depends on the nature of the preprocessor; some preprocessors are only capable of performing relatively simple textual substitutions and macro expansions,

while others have the power of full-fledged programming languages.

output a canonical “web language,” like JavaScript or CSS.

More a dialect, less a language.

Common Arguments

Common ArgumentsI know CSS/JavaScript why do I need

to learn Sass/CoffeeScript?



Compiler? I don’t need no stinking compiler!!



Large learning curve




Large learning curve


Convince me!!

Why do we have preprocessors?

• Fill a void or short-coming

• Streamline development

• Ease of use

How to end the argument• Don’t be afraid to walk away

• Give them something to think about

• In regards to pre-processors, history is on the pre-processor side

• CSS4 will have variables

• JavaScript Next (6.0) will have arrow functions
