What is a Shortcode in WordPress?

Shortcodes in WordPress are compact snippets enclosed in square brackets ([]) that allow users to execute PHP code within WordPress posts, pages, and widgets without writing any code directly. Introduced in WordPress version 2.5, shortcodes make it easy for users to embed files or create complex page elements using simple, readable tags.
