You can represent time statements in most western languages where | |
a prefix and/or suffix is used. | |
The default case is to use suffix only (as in English), which you | |
do by providing the `suffixAgo` and `suffixFromNow` settings in | |
the strings hash (earlier versions of timeago used the deprecated | |
`ago` and `fromNow` options). If present, they are used. | |
2 minutes [suffixAgo] | |
2 minutes [suffixFromNow] |
