Benchmark: Ramda vs. Lodash 2021

Ramda vs. Lodash 2021 (version: 0)

Compares performance on the same task using Lodash vs two styles of Ramda vs two styles of "native" Javascript. In all cases the task is pulling "counter" property from each item in an array, filtering out odd items, squaring them, then returning those squared values that have less than two digits.

Script Preparation code:

var data = _.range(10000).map(function(i) {
  return {
    counter: i
  }
});

function isOdd(num) {
  return num % 2 === 1;
}

function square(num) {
  return num * num;
}

function lessThanThreeDigits(num) {
  return num.toString().length < 3;
}

Tests:

Lodash
var result = _.chain(data) .pick('counter') .filter(isOdd) .map(square) .filter(lessThanThreeDigits) .value();
Ramda without relying on currying or composition
var result = R.filter(lessThanThreeDigits, R.map(square, R.filter(isOdd, R.pluck('counter', data))));
Ramda with currying and composition
var result = R.pipe( R.pluck('counter'), R.filter(isOdd), R.map(square), R.filter(lessThanThreeDigits) )(data);

Let's break down the provided JSON to understand what is being tested.

**Benchmark Definition**

The benchmark compares the performance of three different approaches:

1. **Lodash**: Uses the `_.chain()` function to chain multiple functions together, which allows for more readable code but potentially slower execution due to the overhead of creating a new scope.
2. **Ramda without currying or composition**: Uses individual functions (`R.filter()`, `R.map()`, etc.) without chaining them together. This approach can be faster since it avoids the overhead of creating a new scope.
3. **Ramda with currying and composition**: Uses Ramda's functional programming style, where functions are composed using `R.pipe()` to create a pipeline of operations. This approach is often more concise but may incur additional overhead due to the creation of function calls.

**Pros and Cons**

* **Lodash (`.chain()`)**:
	+ Pros: More readable code, easier to understand the intent.
	+ Cons: Potentially slower execution due to scope overhead.
* **Ramda without currying or composition**:
	+ Pros: Faster execution, avoids scope overhead.
	+ Cons: Code may look less concise and less readable.
* **Ramda with currying and composition**:
	+ Pros: More concise code, can be easier to read and understand the intent.
	+ Cons: May incur additional overhead due to function call creation.

**Library and Purpose**

* **Lodash**: A popular utility library for JavaScript that provides a wide range of functions for tasks such as string manipulation, array processing, and more. The `.chain()` function is used to chain multiple functions together, making it easier to write readable code.
* **Ramda**: A functional programming library for JavaScript that provides a set of higher-order functions (functions that take other functions as arguments) for tasks such as data transformation, filtering, and mapping.

**Special JS Features or Syntax**

None mentioned in the provided JSON.

**Other Alternatives**

* For an alternative approach to Ramda's currying and composition, one could use vanilla JavaScript functions like `map()`, `filter()`, and `reduce()`.
* Another option for a library similar to Lodash is **Underscore.js**, which provides many of the same utility functions.

**Benchmarking Considerations**

When benchmarking performance differences between these approaches, it's essential to consider factors such as:

* Code readability vs. execution speed
* Overhead of function call creation and scope management
* Optimizations for specific use cases or datasets

Keep in mind that this benchmark is comparing different coding styles and libraries, so the results may not be directly applicable to real-world use cases.

By understanding these factors and considering alternative approaches, developers can make informed decisions about which code style and library to use depending on their specific needs.
