Unist Utility to Modify Children

unist-util-modify-children is a utility within the unist (Universal Syntax Tree) ecosystem designed to create a reusable function for directly modifying the children of a parent node in an AST. The current stable version is 4.0.0, which notably moved to ESM-only and requires Node.js 16+. Releases generally follow semantic versioning, with major versions introducing breaking changes like environment requirements or module system shifts. A key differentiator and strong recommendation from its maintainers is that most users should probably use `unist-util-visit` instead, as `unist-util-modify-children` is intended for very specific, advanced scenarios where direct, in-place manipulation of child arrays is explicitly required and other traversal utilities are insufficient.
