The Shadow Over Chelsea

The year is 1979. A deep malaise stalks Jimmy Carter's America. In New York, the police have printed fliers warning tourists to stay off the streets after 6PM. Vigilantes keep the peace on the subway. Sid Vicious died in his hotel room last week. What a time to be alive.

New York was a breeding ground for the mystical and occult in the 1970s, and at the center of it was a magic shop called The Hidden Mirror. This shop, run by on-again, off-again lovers Harry Abel and E Krasinski, was the crossover point for astrologers, neopagans, Pythagorans, and all the other occult groups springing up in the Age of Aquarius.

The React Context API in an alternate universe

Overview

Context is "just" a prop with special behavior, like children or key. It implicitly propagates from elements to their children, unless it is explicitly overridden.

Context can be provided as a prop (to elements) or via the children object's withContext method. Context can be consumed as a prop (to components) or by using a function in children.
