JavaScript State pattern

The state object is where you store property values that belongs to the component . When the state object changes, the component re-renders.

A state variable is one of the set of variables that are used to describe the mathematical “state” of a dynamical system . Intuitively, the state of a system describes enough about the system to determine its future behaviour in the absence of any external forces affecting the system.

No state is not a reserved word . I don’t think there are any specific to react but there are reserved keywords in javascript language.

There are only two possible and equally simple strategies here — either derive the polar or the cartesian coordinates . Both functions are based on the same unique state so it should never be possible for tests to pass individually but fail when cross referenced.
