js 大括号含义

/*
* Strings in timeago are "composed" with prefixes, words and suffixes. This
* makes their detection by our translating system impossible. Use all literal
* strings we're using with a translation mark here so the extractor can do its
* job.

{
_t('less than a minute ago');
_t('about a minute ago');
_t('%d minutes ago');
_t('about an hour ago');
_t('%d hours ago');
_t('a day ago');
_t('%d days ago');
_t('about a month ago');
_t('%d months ago');
_t('about a year ago');

上面的声明是咋回事？
浏览器没报错（需要google chrome支持）

Answer 1

就是一个对象，是用字面量声明对象。
比如var test = {a：1，b：2}；
那个就有了一个test对象，这个对象有两个属性：a和b，值是1和2。
只是你上面那个对象没有变量指向它。
