Benchmark: Test object emptyness (for .. in vs Object.keys vs Object.values vs lodash.isEmpty vs jquery.isEmptyObject)

Test object emptyness (for .. in vs Object.keys vs Object.values vs lodash.isEmpty vs jquery.isEmptyObject) (version: 1)

Tests performance of different techniques and libraries individually and with varying data to observe possible variations.

Comparing performance of: forIn emptyPlainObject vs forIn emptyNullProtoObject vs forIn mediumObject vs forIn largeObject vs forIn veryLargeObject vs objectKeys emptyPlainObject vs objectKeys emptyNullProtoObject vs objectKeys mediumObject vs objectKeys largeObject vs objectKeys veryLargeObject vs objectValues emptyPlainObject vs objectValues emptyNullProtoObject vs objectValues mediumObject vs objectValues largeObject vs objectValues veryLargeObject vs lodashIsEmpty emptyPlainObject vs lodashIsEmpty emptyNullProtoObject vs lodashIsEmpty mediumObject vs lodashIsEmpty largeObject vs lodashIsEmpty veryLargeObject vs jqueryIsEmptyObject emptyPlainObject vs jqueryIsEmptyObject emptyNullProtoObject vs jqueryIsEmptyObject mediumObject vs jqueryIsEmptyObject largeObject vs jqueryIsEmptyObject veryLargeObject
