'''Modularity''' is the degree to which a [[system]]'s components may be separated and recombined, often with the benefit of flexibility and variety in use.<ref name="MWModular">{{cite web |url=https://www.merriam-webster.com/dictionary/modularity |title=modular |work=Merriam-Webster |publisher=Merriam-Webster, Inc |date=17 May 2018 |access-date=18 May 2018}}</ref> The concept of modularity is used primarily to reduce [[complexity]] by breaking a system into varying degrees of interdependence and independence across and "hide the complexity of each part behind an [[abstraction]] and interface".<ref name="BaldwinDesign00">{{cite book |chapter-url=https://books.google.com/books?id=oaBOuo4mId8C&pg=PA63 |chapter=Chapter 3: What Is Modularity? |title=Design Rules: The power of modularity |author=Baldwin, C.Y. |author2=Clark, K.B. |publisher=MIT Press |pages=63–92 |year=2000 |isbn=9780262024662 |access-date=18 May 2018}}</ref> However, the concept of modularity can be extended to multiple disciplines, each with their own nuances.

[[Composability]] is one of the tenets of [[functional programming]].  This makes functional programs modular. <ref name=":1">{{Cite book |last=Wlaschin |first=Scott |title=Domain Modeling Made Functional: Tackle Software Complexity with Domain-Driven Design and F# |date=4 February 2018 |publisher=Pragmatic Bookshelf |isbn=978-1680502541}}</ref>
