Code glossary

A useful list of programming jargon to solve your naming problems.

Adapter: a design pattern that translates one interface for a class into a compatible interface.

Admin: short for 'administrator'; very commonly used in speech or online to refer to the systems person in charge on a computer. Common constructions on this include sysadmin and site admin (emphasizing the administrator's role as a site contact for email and news).

Counter: a variable or user interface that counts occurrences or repetitions of some phenomena or event.

Cycle custom elements decouple the component's abstraction from its implementation.

When you use a React component like

<div>
  <NewHotness />
</div>

You are pulling in that specific NewHotness component. You actually had to explicity import the NewHotness component before using it.
