Benchmark: objk a ssign vs spread

Tests:

spreader
const firstObject = { sampleData: 'Hello world' } const secondObject = { moreData: 'foo bar' } const finalObject = { ...{}, ...firstObject, ...secondObject };
obj./assiogn
const firstObject = { sampleData: 'Hello world' } const secondObject = { moreData: 'foo bar' } const finalObject = Object.assign({}, firstObject, secondObject);

**Benchmark Definition JSON**

The provided JSON represents a JavaScript benchmark definition. Here's what's being tested:

* The benchmark compares two approaches:
	+ **Spreading operator (`...`)**: This approach uses the spread operator to merge multiple objects into a single object.
	+ **Object.assign() method**: This approach uses the `Object.assign()` method to merge multiple objects into a single object.

**Options Compared**

The two options being compared are:

1. Spreading operator (`...`): This operator allows you to merge multiple objects into a single object by spreading their properties onto a target object.
2. Object.assign() method: This method allows you to merge one or more source objects into a target object.

**Pros and Cons**

Here's a brief summary of the pros and cons of each approach:

* **Spreading operator (`...`)**:
	+ Pros:
		- More concise and readable code
		- Can handle nested objects
	+ Cons:
		- Not supported in older browsers (e.g., Internet Explorer)
		- May not work as expected with certain types of data (e.g., arrays)
* **Object.assign() method**:
	+ Pros:
		- Widely supported across modern browsers and Node.js versions
		- Allows for more control over the merging process
	+ Cons:
		- More verbose code compared to the spreading operator

**Library Used**

In this benchmark, no specific library is used. The `Object` object and its methods (e.g., `assign()`) are built-in JavaScript objects.

**Special JS Feature or Syntax**

The benchmark uses the spread operator (`...`), which was introduced in ECMAScript 2018 (ES9). It's a relatively new feature, but it has gained popularity due to its concise and readable syntax. If you're using an older version of JavaScript that doesn't support this feature, you'll need to use the `Object.assign()` method instead.

**Other Alternatives**

If you want to explore alternative approaches for merging objects in JavaScript, here are a few options:

* **Lodash's `merge()` function**: Lodash is a popular utility library for JavaScript. Its `merge()` function provides a flexible way to merge multiple objects into a single object.
* **Ramda's `obj` function**: Ramda is another functional programming library for JavaScript. Its `obj` function provides a concise way to merge multiple objects into a single object.
* **Object merging using destructuring**: You can also use destructuring syntax to merge objects by assigning properties from one object to another.

Keep in mind that these alternatives might have different trade-offs and performance characteristics compared to the spreading operator or Object.assign() method.
