Summary

The check for "is this value an element made by this library?" is now named isMDElement, after the MDElement type it narrows to. The old name, isMarkdown, still works.

• isMDElement(value) replaces isMarkdown(value). It does the same thing.
• isMarkdown stays exported as an alias, so existing code keeps working.
• The old name suggested a test for Markdown text. A string of Markdown was never an element, and gives false.

Usage

import * as md from '@streetsidesoftware/markdown-toolkit';

md.isMDElement(md.p('Hi'));
// true
md.isMDElement('Hi');
// false
