JIT（just in time）
- Real-time compilation, just-in-time compilation.
- Profile-Based Optimization, optimizes while running, and obtains the most optimized code as possible based on runtime information over time, which is suitable for development and debugging.
AOT（ahead of time）
- Pre-compiled, statically compiled.
- Compile the binary code during installation to improve the execution speed at runtime. Can increase speed (especially startup time), reduce memory footprint (not JIT) and improve memory recycling.
- Use AOT compilation mode, the template is type-safe, suitable for deployment and release.
