This benchmark compares the performance of lodash's `union` function with native JavaScript code for creating an array of unique values from all given arrays. The lodash `union` function creates an array of unique values, in order, from all given arrays. The native JavaScript code uses the `Array.prototype.concat()` method combined with `new Set()` to achieve the same result.
This benchmark compares the performance of lodash's `has` function with native JavaScript code for checking if an object has a specific property. The lodash `has` function checks if `path` is a direct property of `object`. The native JavaScript code uses the `in` operator to check if an object has a specific property.
This benchmark compares the performance of lodash's `isEmpty` function with native JavaScript code for checking if an object is empty. The lodash `isEmpty` function checks if a value is an empty object, collection, map, or set. The native JavaScript code checks if an object has no own enumerable string keyed properties.
