This video explains how the JVM (Java Virtual Machine) makes Java, Kotlin, and Scala faster through Just-in-Time (JIT) compilation.”

We break down the JVM from beginner to advanced concepts:
- Why the JVM exists and how it enables "Write Once, Run Anywhere"
- Bytecode, interpretation, and Just-in-Time (JIT) compilation
- How the JVM optimizes code on the fly (inlining, loop unrolling, escape analysis)
- AOT vs JIT: what’s the difference?

ByteMonk

The JVM uses just-in-time (JIT) compilation to continuously optimize code while it runs, unlike traditional ahead-of-time compilation. It starts by interpreting bytecode, then compiles frequently used methods into optimized machine code. This adaptive approach allows JVM applications to improve performance over time by learning from real execution patterns, making it ideal for long-running services despite slower startup times.
