Code execution is the ultimate tool call. Once an LLM can run its own code, it can run loops, access APIs, and extract the result.

Giving an LLM a code sandbox massively increases its capabilities, but managing VM lifecycles is a pain.
Introducing foreverVM, a Python REPL-as-a-service. Under the hood, we swap between memory and durable storage. To you (and your agent) it acts like an always-on REPL.

The trick is a technique called fractional indexing, in which indices are fractions rather than integers. Can you solve the exercise and implement it?

Instead of keeping the todos in an array, try keeping them in a map.
We can give each todo an index property. The ordered list of todos is an array of the map values sorted by the index property. To move a todo, simply set a new index!
It sounds good in theory, but…

Here’s a curious fact about Yjs. Once you add a shared type to a document, it can never be moved. You can change what it contains and you can delete it, but you can’t move it from one place to another.
That means moving array elements really means deleting and re-adding them.

In Learn Yjs lesson 3, we look at another classic app: the todo list!
This demo allows each client to reorder the todos and toggle their checkboxes.

Not so fast! This demo happens to be working because updates are synchronous. Every time the button gets clicked, the other client instantly receives the update.
When we add a little latency, the counter breaks!

Like JavaScript’s Map object, a Yjs map holds key/value pairs.
Here you can see how Yjs syncs the values between two maps, with latency added to simulate a network connection.

A Yjs document is like a container for your state. To read and update that state, Yjs has a feature called shared types. They’re similar to JavaScript data structures such as Map — except shared types automatically sync between clients.
All in all, there are six shared types:
