Plural variants are used whenever a numeric value is being dynamically passed into a translation string to ensure the accuracy and readability of sentences when there are zero, one or multiple things being referenced.
Singular and plural indicators
For plurals, we create different versions of a key followed by an underscore and the plural or singular indicator it represents.
{
"key_zero": "zero",
"key_one": "singular",
"key_two": "two",
"key_few": "few",
"key_many": "many",
"key_other": "other"
}
Most commonly, we will use the following indicator suffixes:
_zerofor the string rendered when there are 0 of count_onefor the string rendered when there is 1 of count_otherfor the string rendered when there is more than 1 of count
Using count indicators
In our JSON translation file:
"status_testing_zero": "We are not missing test records or accounts for any library.",
"status_testing_one": "We are missing test records or accounts for {{count}} library.",
"status_testing_other": "We are missing test records or accounts for {{count}} libraries."
In our code, we use the string without the underscore and number, and the string will automatically adapt to count.
t('status_testing', {count: 0}); // -> "We are not missing test records or accounts for any library."
t('status_testing', {count: 1}); // -> "We are missing test records or accounts for 1 library."
t('status_testing', {count: 34}); // -> "We are missing test records or accounts for 34 libraries."
