HOW

equals performs deep structural equality check on primitives, nested objects, and arrays
equals handles circular references without infinite recursion
equals supports custom tester functions for specialized value comparisons
equals with strictCheck true distinguishes between undefined properties and omitted properties
isA verifies object type tags matching standard constructor names
isError returns true for Error instances and false for non-error values
emptyObject returns true for empty objects or empty arrays and false for non-empty structures
getObjectKeys extracts own enumerable string keys from objects
getObjectSubset extracts matching properties and subsets from complex nested structures
getPath traverses nested object hierarchies with dot notation and returns traversed value and metadata
pathAsArray decomposes dot and bracket property paths into path segment arrays
partition splits an array into two arrays based on a predicate function
iterableEquality evaluates equality for Sets and Maps independent of insertion order where applicable
arrayBufferEquality compares ArrayBuffer contents byte by byte
