Mozilla recently released the awesome L20n or localization 2.0. In their own words L20n is

an open source, localization-specific scripting language used to process gender, plurals, conjugations, and most of the other quirky elements of natural language.

Their js implementation is on the github L20n repository.

Localization support in legacy browsers is poor   Originally  this was due to phrases in the ECMAScript language spec that look like this   Number prototype toLocaleString   Produces a string value that represents the value of the Number formatted according to the conventions of the host environment   s current locale  This function is implementation-dependent  and it is permissible  but not encouraged  for it to return the same thing as toString   Every localization method defined in the spec is defined as  quot implementation-dependent quot   which results in a lot of inconsistencies   In this instance  Chrome Opera and Safari would return the same thing as  toString     Firefox and IE will return locale formatted strings  and IE even includes a thousand separator  perfect for currency strings    Chrome was recently updated to return a thousands-separated string  though with no fixed decimal  For modern environments  the ECMAScript Internationalization API spec  a new standard that complements the ECMAScript Language spec  provides much better support for string comparison  number formatting  and the date and time formatting  it also fixes the corresponding functions in the Language Spec  An introduction can be found here  Implementations are available in   Chrome 24 Firefox 29 Internet Explorer 11 Opera 15  There is also a compatibility implementation  Intl js  which will provide the API in environments where it doesn t already exist  Determining the user s preferred language remains a problem since there s no specification for obtaining the current language   Each browser implements a method to obtain a language string  but this could be based on the user s operating system language or just the language of the browser     navigator userLanguage for IE  navigator language for others var lang   navigator language    navigator userLanguage   A good workaround for this is to dump the Accept-Language header from the server to the client   If formatted as a JavaScript  it can be passed to the Internationalization API constructors  which will automatically pick the best  or first-supported  locale  In short  you have to put in a lot of the work yourself  or use a framework library  because you cannot rely on the browser to do it for you  Various libraries and plugins for localization   Mantained by an open community  no order     Polyglot js - AirBnb s internationalization library Intl js - a compatibility implementation of the Internationalisation API i18next  home  for i18n  incl  jquery plugin  translation ui      moment js  home  for dates numbro js  home   was numeral js  home   for numbers and currency l10n js   home  L10ns  home  tool for i18n workflow and complex string formatting jQuery Localisation  plugin    home  YUI Internationalization support jquery i18Now for dates browser-i18n with support to pluralization counterpart is inspired by Ruby s famous I18n gem jQuery Globalize jQuery s own i18n library js-lingui - MessageFormat implementation for JS  ES2016  and React   Others    jQuery Globalization  plugin  requirejs-i18n Define an I18N Bundle with RequireJS   Feel free to add edit

Some of it is native  the rest is available through libraries   For example Datejs is a good international date library   For the rest  it s just about language translation  and JavaScript is natively Unicode compatible  as well as all major browsers

You can also try another library - https   github com wikimedia jquery i18n    In addition to parameter replacement and multiple plural forms  it has support for gender a rather unique feature of custom grammar rules that some languages need
