Benchmark: Lodash has x chaining props

Script Preparation code:

var resultado = {
    data : {
statusProcessamento : {
      messagem: "ola"
        }
    }
}

Tests:

Js
if(resultado && resultado.data && resultado.data.statusProcessamento && resultado.data.statusProcessamento.message) { return resultado }
Lodash
if(_.has(resultado, "data.statusProcessamento.message")){ return resultado }

I'll break down the benchmark and explain what's being tested, compared, and analyzed.

**Benchmark Overview**

The benchmark measures how fast two different approaches can access nested properties in an object using JavaScript. The test cases use either built-in JavaScript features or the popular utility library Lodash.

**Options Compared**

There are two options being compared:

1. **JavaScript Built-in Approach**: This approach uses only native JavaScript methods to access the nested property.
2. **Lodash Approach**: This approach uses the Lodash library to simplify the access to the nested property.

**Pros and Cons of Each Approach**

**JavaScript Built-in Approach**

Pros:

* No external dependencies required (no additional library load)
* Can be a good choice when optimizing for minimalism or performance-critical code

Cons:

* May require more complex and verbose code to achieve the same result
* Can lead to slower execution times due to additional overhead of method calls

**Lodash Approach**

Pros:

* Simplifies the access to nested properties, making the code easier to read and maintain
* Often leads to faster execution times since Lodash methods are optimized for performance

Cons:

* Requires an external dependency (loading Lodash library)
* May add unnecessary overhead due to the library's presence

**Other Considerations**

When deciding between these approaches, consider the trade-offs between readability, maintainability, and performance. If simplicity and ease of understanding are essential, the Lodash approach might be a better choice. However, if optimization for minimalism or avoiding external dependencies is crucial, the JavaScript built-in approach could be a better fit.

**Library: Lodash**

Lodash is a popular utility library that provides a range of functions for working with arrays, objects, and other data structures in JavaScript. The `has` function used in the benchmark is specifically designed to check if an object has a particular property, making it a convenient tool for accessing nested properties.

**Special JS Feature/Syntax**

There isn't any special JavaScript feature or syntax mentioned in this benchmark. Both test cases rely on standard JavaScript language features and Lodash library functionality.

**Alternatives**

Other alternatives to Lodash could include:

* Using other utility libraries like Underscore.js, Ramda, or Moment.js
* Implementing custom functions for accessing nested properties
* Utilizing alternative data structures like JSON objects or Map data structures

Keep in mind that each of these alternatives would require trade-offs in terms of performance, readability, and maintainability.
