JavaScript is primarily an interpreted language, although modern JavaScript engines use a combination of interpretation and Just-In-Time (JIT) compilation techniques to improve performance. Traditionally, JavaScript code is executed directly by the browser’s JavaScript engine, such as V8 in Chrome or SpiderMonkey in Firefox, without requiring a separate compilation step. This allows JavaScript to be executed immediately as it is read and parsed.
However, to enhance execution speed, contemporary JavaScript engines employ JIT compilation. JIT compilation involves compiling JavaScript code into machine code at runtime, rather than ahead of time. This approach optimizes frequently executed code paths, improving performance compared to straightforward interpretation.
In summary, while JavaScript is fundamentally an interpreted language, modern engines blend interpretation with JIT compilation to achieve better execution efficiency. This hybrid approach allows JavaScript to maintain its dynamic, flexible nature while also delivering improved performance in practice.

Cells utilize a variety of mechanisms to sense and respond to oxidative stress, including antioxidant defense systems, DNA repair pathways, and protein quality control processes. While these responses are crucial for maintaining cellular function, their efficiency declines with age, leading to the accumulation of oxidative damage. This contributes to the aging process and the development of age-related diseases. Understanding these pathways provides insights into potential therapeutic strategies to mitigate aging and promote healthy lifespan.
