Example

There are many examples on the website, but here's a comprehensive one:

{{formatMessage (intlGet "messages.post.meta")
    num=post.comments.length
    ago=(formatRelative post.date)}}
var context = {
    post: {
        date    : 1422046290531,
        comments: [/*...*/]
    }
};
 
var intlData = {
    locales : ['en-US'],
    messages: {
        post: {
            meta: 'Posted {ago}, {num, plural, one{# comment} other{# comments}}'
        }
    }
};
 
var template = Handlebars.compile(/* Template source above */);
 
var html = template(context, {
    data: {intl: intlData}
});

This example would render: "Posted 3 days ago, 1,000 comments" to the html variable. The post.meta message is written in the industry standard ICU Message syntax, which you can also learn about on the FormatJS website.
