make developers happy the community mattershelp the community by writing extensible code

make developers happy the community mattershelp the community by writing extensible code others will say nice things about you

Matt Varone“Extensible code makes me happy.”

Ryan Imel“I think the true measure of a quality theme or plugin is how well it works with other plugins and themes - - both those that already exist and those that haven’t been made yet.”

Jake Goldman“What would core do?”

WordPress is modular how do you think plugins work?

WordPress is modular how do you think plugins work? -by using methods like those we just looked at

built with extensible functionsWordPress is comprised of extensible “modules”

build it like WordPressbuild your plugins like you were building WordPress itself
