JavaScript i18n Libraries

Last updated Sep 09, 2021javascriptlibslists

Internationalization is the design and development of a product, application or document content that enables easy localization for target audiences that vary in culture, region, or language.

Each language has different names for the days of the week and the months of the year, they also have different expectations for the structure of dates, such as what order the day, month and year are in.

In number formatting, not only does the character used to delineate number groupings and the decimal portion differ, but the placement of those characters differ as well.

A user using an application should be able to read and write dates and numbers in the format they are accustomed to, following libraries makes this possible.
