Benchmark: 1123dsfsdfsdf - MeasureThat.net

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var a = null;
var b = undefined;
var c = 123;

Tests:

123
if(_.isNil(a)) console.log(123); if(_.isNil(b)) console.log(123); if(_.isNil(c)) console.log(123);
234
if(!a) console.log(123); if(!b) console.log(123); if(!c) console.log(123);

Let's break down the provided JSON data and explain what is tested on MeasureThat.net.

**Benchmark Definition**
The benchmark definition is a JSON object that represents the JavaScript code to be executed during the benchmarking process. In this case, there are two benchmark definitions:

1. The first one defines an array of variables `a`, `b`, and `c` with specific values (null, undefined, and 123 respectively) using the Script Preparation Code.
2. The second benchmark definition is a simple if-conditional statement that checks for the existence of `a`, `b`, and `c` using the Lodash library's `isNil` function.

**Options Compared**
The two benchmark definitions are compared in terms of their execution performance, which is measured by the `ExecutionsPerSecond` value.

**Pros and Cons**

* **Simple Conditional Statement**: The second benchmark definition is a simple if-conditional statement that checks for the existence of variables. This approach is easy to understand and maintain, but it might not be representative of real-world scenarios where conditional statements are used extensively.
	+ Pros: Easy to write and maintain.
	+ Cons: May not accurately represent real-world usage patterns.
* **Variable Initialization**: The first benchmark definition initializes variables with specific values using the Script Preparation Code. This approach can provide more accurate results, but it might be less efficient due to the overhead of variable initialization.
	+ Pros: Can provide more accurate results.
	+ Cons: May introduce unnecessary overhead.

**Lodash Library**
The Lodash library is used in the second benchmark definition to implement the `isNil` function. The purpose of this library is to provide a set of functional programming utilities, including functions for working with arrays, objects, and other data structures.

**Special JS Feature or Syntax**
There are no special JavaScript features or syntax used in these benchmark definitions. However, it's worth noting that the use of `undefined` as a variable value might be considered unusual in some contexts.

**Alternatives**

* **Alternative Script Preparation Code**: Instead of using the Script Preparation Code to initialize variables, the benchmark could use other methods, such as using the `var` keyword with the `let` or `const` keywords.
* **Alternative Conditional Statements**: The benchmark could use different conditional statements, such as ternary operators or logical operators (e.g., && and ||).
* **Alternative Libraries**: Other libraries, such as Underscore.js or Ramda, could be used to implement the `isNil` function instead of Lodash.

It's worth noting that MeasureThat.net is a tool for measuring JavaScript performance, and the benchmark definitions are designed to test specific aspects of JavaScript execution. The options compared in these benchmark definitions are intended to highlight the importance of proper variable initialization and conditional statement optimization in real-world scenarios.
