Partial Application
partial()
takes the second parameter offilesize()
and returns a new function with the configuration applied upon execution. This can be used to reduceObject
creation if you callfilesize()
without caching thedescriptor
in lexical scope.import {partial} from "filesize"; const size = partial({base: 2, standard: "jedec"}); size(265318); // "259.1 KB"
