Bytecode Execution
Bytecode execution is a process where intermediate code (bytecode) generated by a compiler is executed by a virtual machine or interpreter, rather than directly by the hardware. It serves as a platform-independent representation of source code, enabling portability across different systems. This approach is commonly used in languages like Java and Python to abstract away hardware-specific details.
Developers should learn about bytecode execution when working with languages that use virtual machines, such as Java (JVM), Python (CPython), or .NET (CLR), as it is crucial for understanding performance optimization, debugging, and cross-platform deployment. It is particularly important for building applications that need to run on multiple operating systems without recompilation, and for tasks like just-in-time (JIT) compilation and memory management in runtime environments.
