Standard library deep dive
What it is: The Mojo standard library reference that Modular publishes. It documents every built-in type, module, and helper.
Why read it:
- Clarifies which types are cheap values versus heap-backed, so you know when copying is safe.
- Lists traits and methods for each core type, which helps when you are porting Python code.
- Includes GPU- and LayoutTensor-aware packages that are easy to miss elsewhere.
Tips before you click:
- Start with the Core Types section to get a feel for the ownership semantics.
- Use the Collections and Algorithms entries when you’re hunting for helpers (
enumerate,zip, reductions, etc.). - Keep an eye on the GPU and Layout chapters-Modular updates them frequently as MAX evolves.
