Where is the interpreter in JavaScript?

Who compiles JavaScript?
A Compiler It compiles it down to a language that can be understood by the machine. A compiler will take one pass through the code and try to understand what the code does. It will take a program in javascript and write the program in a new language x.

Is Java an interpreter or compiler?
Java is a programming language and computing platform first released by Sun Microsystems in 1995. A Java compiler is a compiler for the Java programming language. A JVM interprets bytecode and a Java interpreter interprets Java. They are different because bytecode and Java are different languages. Bytecode is a low-level language, like machine code.
