/**
 * Deeply compares two values.
 *
 * Supported values are:
 * - Primitives
 * - Boxed observables
 * - Objects, observable objects
 * - Arrays, observable arrays
 * - Typed arrays
 * - Maps, observable maps
 * - Sets, observable sets
 * - Tree nodes (optimized by using snapshot comparison internally)
 *
 * Note that in the case of models the result will be false if their model IDs are different.
 *
 * @param a First value to compare.
 * @param b Second value to compare.
 * @returns `true` if they are the equivalent, `false` otherwise.
