I see the Python Langchain supports the MarkdownHeaderTextSplitter which is needed keep the header hierarchy when chunking documents. But the Javascript Langchain does not seem to support this. Is this something that is coming or should I use Python instead?

Hello @michielvaneerd welcome to langchain community.  
Better if you ask for this feature request here [GitHub - langchain-ai/langchainjs: The agent engineering platform · GitHub](https://github.com/langchain-ai/langchainjs), until otherwise use python.
