Learn how to learn new programming language
Type System
- A type used to be associated with abstract representation, boundary, internal memory representation, allowed operations
- Type extension system
- User defined type
Scope and Lifetime
Scope is the visibility of the object, can be different from lifetime of the object.
Lifetime of an object can be in whole program but maybe only visible in a certain scope.
Control Flow
- Conditonal
- Loop and Iteration
- Local jump and global jump
- Exceptional control flow, such as exit/termination hook of program
Error Handling
- Static error handling, e.g. error check at compilation phase
- Error recovery
- Error propagation
- Stack trace
I/O Operations
Be aware of I/O bound and CPU bound operations
- Disk I/O
- Network I/O
- Endianesss
Encoding and Decoding System
- Character set
- Character/String encoding and decoding
Memory management
Be aware of how Language handling stack and heap by default, how to manipulate it.
- Stack
- Heap
Module system
- How to define a module
- How a program is structured into module
- Module scope and visibility
Packaging system
- binary executable
- library
Sync and Async
If any native async support in Language
Multi Threading
- Thread’s local variable, atomic variable, mutex lock
- Attach and detach threads
- Daemonize threads
Multi Processing
- Fork process, terminate/kill process,
- IPC — Inter Process Communication
