Benchmark: toLocaleLowerCase vs collator

Script Preparation code:

var a = 'FOO BAR';
var b = 'foo bar';

var locale1 = 'en-US'
var locale2 = 'tr'

var collator1 = new Intl.Collator(locale1, { sensitivity: 'accent' });
var collator2 = new Intl.Collator(locale2, { sensitivity: 'accent' });

​x
 
var a = 'FOO BAR';var b = 'foo bar';​var locale1 = 'en-US'var locale2 = 'tr'​var collator1 = new Intl.Collator(locale1, { sensitivity: 'accent' });var collator2 = new Intl.Collator(locale2, { sensitivity: 'accent' });

Tests:

toLocaleLowerCase (en-US)
a.toLocaleLowerCase(locale1) === b.toLocaleLowerCase(locale1)
a.toLocaleLowerCase(locale1) === b.toLocaleLowerCase(locale1)
collator (en-US)
collator1.compare(a, b) === 0
collator1.compare(a, b) === 0
toLocaleLowerCase (tr)
a.toLocaleLowerCase(locale2) === b.toLocaleLowerCase(locale2)
a.toLocaleLowerCase(locale2) === b.toLocaleLowerCase(locale2)
collator (tr)
collator2.compare(a, b) === 0
collator2.compare(a, b) === 0

Let's break down the provided benchmark and explain what is being tested.

Benchmark Overview

The benchmark compares the performance of two approaches: toLocaleLowerCase and an internationalization library called Intl.Collator. The test cases measure the execution speed of these approaches for both English (en-US) and Turkish (tr) locales.

Script Preparation Code

The script preparation code sets up the environment for the benchmark. It defines:

Two strings: a and b, containing the same text but with different casing (FOO BAR and foo bar).
Two locale variables: locale1 (en-US) and locale2 (tr).
Two collator objects: collator1 and collator2. These objects are created using the Intl.Collator API, which is a built-in JavaScript library for internationalization.

Html Preparation Code

There is no HTML preparation code provided, which means that the benchmark does not involve any HTML-related operations or interactions.

Individual Test Cases

The benchmark consists of four test cases, each measuring the performance of one of the two approaches:

toLocaleLowerCase (en-US): Measures the execution speed of the toLocaleLowerCase method for English.
collator (en-US): Measures the execution speed of the Intl.Collator library for English.
toLocaleLowerCase (tr): Measures the execution speed of the toLocaleLowerCase method for Turkish.
collator (tr): Measures the execution speed of the Intl.Collator library for Turkish.

Performance Comparison

The benchmark measures the number of executions per second (ExecutionsPerSecond) for each test case, which indicates the relative performance of the two approaches.

Pros and Cons

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

toLocaleLowerCase:
- Pros: widely supported, simple to use.
- Cons: may not handle edge cases or cultural nuances accurately.
Intl.Collator:
- Pros: more accurate for handling cultural differences, can be used for sorting and comparison tasks beyond just casing.
- Cons: requires more setup and configuration, may have slower execution speeds due to the additional overhead.

Intl.Collator Library

The Intl.Collator library is a built-in JavaScript API that provides support for internationalization and localization. It allows developers to work with different languages, scripts, and locales in a consistent and reliable way. The library offers various features beyond just casing, such as:

Sorting and comparison
Casing (title case, uppercase, lowercase)
Unicode normalization

Other Alternatives

If you need more advanced internationalization or localization capabilities, consider the following alternatives:

ICU (International Components for Unicode): a comprehensive library that provides support for various languages, scripts, and locales.
moment.js: a popular date and time manipulation library that also offers internationalization features.

Keep in mind that these alternatives may have different performance characteristics, feature sets, or learning curves compared to the Intl.Collator library.

Let's break down the provided benchmark and explain what is being tested.

**Benchmark Overview**

The benchmark compares the performance of two approaches: `toLocaleLowerCase` and an internationalization library called `Intl.Collator`. The test cases measure the execution speed of these approaches for both English (en-US) and Turkish (tr) locales.

**Script Preparation Code**

The script preparation code sets up the environment for the benchmark. It defines:

1. Two strings: `a` and `b`, containing the same text but with different casing (`FOO BAR` and `foo bar`).
2. Two locale variables: `locale1` (en-US) and `locale2` (tr).
3. Two collator objects: `collator1` and `collator2`. These objects are created using the `Intl.Collator` API, which is a built-in JavaScript library for internationalization.

**Html Preparation Code**

There is no HTML preparation code provided, which means that the benchmark does not involve any HTML-related operations or interactions.

**Individual Test Cases**

The benchmark consists of four test cases, each measuring the performance of one of the two approaches:

1. `toLocaleLowerCase (en-US)`: Measures the execution speed of the `toLocaleLowerCase` method for English.
2. `collator (en-US)`: Measures the execution speed of the `Intl.Collator` library for English.
3. `toLocaleLowerCase (tr)`: Measures the execution speed of the `toLocaleLowerCase` method for Turkish.
4. `collator (tr)`: Measures the execution speed of the `Intl.Collator` library for Turkish.

**Performance Comparison**

The benchmark measures the number of executions per second (ExecutionsPerSecond) for each test case, which indicates the relative performance of the two approaches.

**Pros and Cons**

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

1. `toLocaleLowerCase`:
	* Pros: widely supported, simple to use.
	* Cons: may not handle edge cases or cultural nuances accurately.
2. `Intl.Collator`:
	* Pros: more accurate for handling cultural differences, can be used for sorting and comparison tasks beyond just casing.
	* Cons: requires more setup and configuration, may have slower execution speeds due to the additional overhead.

**Intl.Collator Library**

The `Intl.Collator` library is a built-in JavaScript API that provides support for internationalization and localization. It allows developers to work with different languages, scripts, and locales in a consistent and reliable way. The library offers various features beyond just casing, such as:

* Sorting and comparison
