The hook returns the new object after a content change. * * A chart needs this hook because the chart library rebuilds and redraws the whole chart when the identity of its React children changes. A caller that builds a `series` array inside its own render supplies a new array on each render, and every memo below that point then misses. A comparison of the contents costs one walk over the points, which is far less than one redraw of the chart. * * The comparison treats a function by its identity, because two functions with the same body can still behave differently. Therefore a caller that supplies a new function on each render, such as an inline formatter, gets a new object from this hook on each render. */ export declare const useStableValue: (value: ValueType) => ValueType; //# sourceMappingURL=useStableValue.d.ts.map
