#Why Functional Programming Matters (to me)

This is my response to being asked not to use functional programming techniques.

###What I mean by "Functional Programming" Different people mean different things by "Functional Programming". Here's what it means to me:

Functions are first class, fundamental atoms of software, and proper functional programming languages allows passing functions as arguments, assigning them to variables, and composing them together to form new functions.
Strong Static Typing prevents many common programming errors automatically.
Null pointer dereferences can by virtually eliminated using Optional/Option/Maybe/Either data types to explicitly represent empty or error conditions.
Together with sum types, strongly typed languages can automatically perform local totality checking, informing the programmer when a logical branch is not handled.

The issue:

..mobile browsers will wait approximately 300ms from the time that you tap the button to fire the click event. The reason for this is that the browser is waiting to see if you are actually performing a double tap.

(from a new defunct https://developers.google.com/mobile/articles/fast_buttons article)

touch-action CSS property can be used to disable this behaviour.

touch-action: manipulation The user agent may consider touches that begin on the element only for the purposes of scrolling and continuous zooming. Any additional behaviors supported by auto are out of scope for this specification.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
