A pack of functions for working with Sets.
📦 Node.js,
🌐 Web,
📜 Files,
📰 Docs,
📘 Wiki.
A Set is a collection of unique values. This package includes common set functions related to querying about sets, generating them, comparing one with another, finding their size, adding and removing elements, obtaining its properties, getting a part of it, getting a subset elements in it, finding an element in it, performing functional operations, manipulating it in various ways, combining together sets or its elements, of performing set operations upon it.
All functions except from*() take set as 1st parameter. Methods like
concat() are pure and do not modify the set itself, while methods like
concat$() do modify (update) the set itself.
This package is available in Node.js and Web formats. The web format
is exposed as extra_set standalone variable and can be loaded from
jsDelivr CDN.
Stability: Experimental.
