Runtime Interpretation
Runtime interpretation is a programming concept where source code is executed directly by an interpreter at runtime, without prior compilation into machine code. It involves reading, parsing, and executing code line-by-line or statement-by-statement, often with dynamic typing and on-the-fly error checking. This approach enables flexibility, such as dynamic code modification and cross-platform execution, but typically at the cost of performance compared to compiled languages.
Developers should learn runtime interpretation when working with scripting languages like Python, JavaScript, or Ruby, as it allows for rapid prototyping, debugging, and dynamic features like eval() functions. It's essential for tasks requiring high flexibility, such as web development, automation scripts, or data analysis, where quick iteration and cross-platform compatibility are prioritized over raw execution speed. Understanding this concept helps in optimizing code for interpreted environments and choosing the right tool for the job.
