@formatjs/ecma402-abstract

What is @formatjs/ecma402-abstract?

@formatjs/ecma402-abstract is a library that provides abstract operations for the ECMAScript Internationalization API (ECMA-402). It is used to implement the low-level operations required for internationalization features such as formatting dates, numbers, and strings according to different locales.

What are @formatjs/ecma402-abstract's main functionalities?

DateTime Formatting

This feature allows you to format dates according to a specific locale. The code sample demonstrates how to format the current date in the 'en-US' locale with options for year, month, and day.

const { FormatDateTime } = require('@formatjs/ecma402-abstract');
const date = new Date();
const options = { year: 'numeric', month: 'long', day: 'numeric' };
const formattedDate = FormatDateTime('en-US', date, options);
console.log(formattedDate);

Number Formatting

This feature allows you to format numbers according to a specific locale. The code sample demonstrates how to format a number as a currency in the 'en-US' locale.

const { FormatNumber } = require('@formatjs/ecma402-abstract');
const number = 1234567.89;
const options = { style: 'currency', currency: 'USD' };
const formattedNumber = FormatNumber('en-US', number, options);
console.log(formattedNumber);

String Collation

This feature allows you to compare strings according to a specific locale. The code sample demonstrates how to compare two strings in the 'en-US' locale.

const { CompareStrings } = require('@formatjs/ecma402-abstract');
const str1 = 'apple';
const str2 = 'banana';
const comparison = CompareStrings('en-US', str1, str2);
console.log(comparison);

Other packages similar to @formatjs/ecma402-abstract

intl

The 'intl' package provides the ECMAScript Internationalization API as a polyfill. It offers similar functionalities for formatting dates, numbers, and strings according to different locales. However, it is more of a polyfill for environments that do not support the Internationalization API natively.

globalize

The 'globalize' package provides a comprehensive set of internationalization features, including date and number formatting, message translation, and pluralization. It is more feature-rich compared to @formatjs/ecma402-abstract and is built on top of the Unicode CLDR data.

i18next

The 'i18next' package is a powerful internationalization framework for JavaScript. It focuses more on translation and localization of strings rather than low-level formatting operations. It is often used in conjunction with other libraries for complete internationalization solutions.
