Agenda:

• Types of Programming: Understanding compiled and interpreted languages.
• Compilation vs Interpretation: Differentiating preprocessing and direct execution.
• JavaScript JIT Compiler: Exploring optimization techniques.
• How JavaScript Engine Uses JIT Compiler: Analyzing performance enhancement through code segment optimization.

JavaScript engines are the backbone of web browsers, handling compilation, interpretation, and Just-In-Time (JIT) compilation. Compiled languages like C++ are preprocessed before execution, while interpreted languages like JavaScript execute line by line. JavaScript engines merge interpretation for flexibility with JIT compilation for performance. The JIT compiler optimizes frequently accessed code segments, boosting speed through techniques like function inlining and loop unrolling. This collaboration ensures both adaptability and efficiency in web application development. Thank you for sharing, Chhoeung Oudam!
