compile(src, lc, plurals)

Recursively compile a string or a tree of strings to JavaScript function sources

If src is an object with a key that is also present in plurals, the key in question will be used as the locale identifier for its value. To disable the compile-time checks for plural & selectordinal keys while maintaining multi-locale support, use falsy values in plurals.

src string | object

the source for which the JS code should be generated

lc string

the default locale

plurals object

a map of pluralization keys for all available locales
