Benchmark: lodash match or string

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min.js"></script>

Script Preparation code:

var a = {code: 123, price: 320, discounted: 320, qty: 2}

Tests:

alt
a.str = Object.entries(a).reduce((acc, [k,v]) => `${acc}${k}${v}` , ""); const str = Object.entries(a).reduce((acc, [k,v]) => `${acc}${k}${v}` , ""); a === str;

**Benchmark Overview**

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks. The provided benchmark definition and test cases measure the performance of two approaches: using the `lodash` library for string matching and an alternative implementation without any libraries.

**Tested Approaches**

The two tested approaches are:

1. **Lodash**: This approach uses the `_.isMatch()` function from the Lodash library to compare two objects.
2. **Alternative Implementation (alt)**: This approach implements a custom string matching logic using `Object.entries()` and `reduce()`. It compares an object's properties with each other.

**Pros and Cons of Each Approach**

1. **Lodash**:
	* Pros:
		+ Concise and readable code
		+ Well-maintained and widely used library
	* Cons:
		+ Adds extra overhead due to the use of a library
		+ May not be optimized for performance in all scenarios
2. **Alternative Implementation (alt)**:
	* Pros:
		+ Optimized for performance, as it avoids using a library
		+ Can be customized and tuned for specific use cases
	* Cons:
		+ Code can be less readable and more verbose compared to Lodash
		+ May require additional maintenance effort to ensure accuracy

**Library: Lodash**

Lodash is a popular JavaScript utility library that provides a wide range of functions for tasks such as array manipulation, object manipulation, and functional programming. The `_.isMatch()` function used in the benchmark checks whether two objects have the same keys and values.

**Special JS Feature/Syntax**

There are no special features or syntax used in this benchmark. The code only uses standard JavaScript features and operators.

**Other Alternatives**

If you're interested in exploring alternative approaches, here are a few options:

1. **Built-in String Matching**: Most modern browsers have built-in string matching functions that can be used instead of Lodash.
2. **Regular Expressions**: Regular expressions can be used for complex string matching and validation tasks.
3. **Homebrew Implementation**: You can also implement your own custom string matching logic using standard JavaScript features, similar to the `alt` implementation in this benchmark.

These alternatives may have their own pros and cons, and some might require additional expertise or library usage.
