Part 9 The Polyglot Mind - Inside JVM & CLR: How Java Bytecode Works on Virtual Machines

In this episode of “The Polyglot Mind,” we dive into VM-based languages like Java and C#. You'll explore how the Java Virtual Machine (JVM) executes bytecode, learn the "Compile Once, Run Everywhere" philosophy, and use tools like javac, java, and javap to compile, run, and inspect Java applications. This is your gateway into virtual machine-based programming!
