unist-util-visit is a utility for traversing and manipulating syntax trees conforming to the Unified Syntax Tree (unist) specification. It allows developers to easily visit each node in the tree and perform actions, supporting different traversal orders (breadth-first, depth-first). This package is essential for working with Markdown, MDX, and other text-based formats processed using the unified ecosystem, enabling efficient manipulation and analysis of abstract syntax trees. It provides a powerful, type-safe API for inspecting and modifying content.
