Code Compilation & Execution Engine

Code compilation is the process of transforming human-readable source into a format that machines can understand, while the execution engine is the part that executes the compiled code.

Code Compilation:

  • A compiler is a software tool that converts source code written in high-level such as C++, Java, or Python into a lower-level language, like machine code or bytecode.

​

  • This process verifies that the code follows the syntax and grammar of the language, allowing for early error detection.

​

  • The outcome of compilation is an executable file (such as .exe or .) that can be executed on a computer.

Execution Engine:

  • After the code is compiled, it becomes ready for execution by the execution.

​

  • The execution engine (such as the JVM for Java) takes charge of loading the compiled code, overseeing memory management, and interpreting the instructions.

​

  • It collabor with the operating system to allocate resources and oversee program execution.

​

  • In languages like JavaScript, the execution directly parses and executes the code without a separate compilation phase.

​

Summary, compilation serves as the preparation stage, while the execution engine is the that ultimately executes the prepared code.
