When a JS code enters the V8, it is compiled into a byte code due to the just in time (JIT) compilation that is used in the virtual machine , therefore the JS code runs faster. Bytecode is an intermediate, high-level language, so in a JVM, they write not only in Java but also in Scala and Kotlin.15 Tem 2019
