It is a common misconception that source code in a scripting language would 
be interpreted as it is.  Instead, code written for ECMAScript 
implementations in browsers, like JavaScript, JScript aso., is compiled into 
bytecode or native machine code.  Only the bytecode, if that, is then 
interpreted/executed by a Virtual Machine (VM).  This applies to several 
other scripting languages that are not based on ECMAScript, too, for example 
PHP and Python.  It is therefore wrong to say “interpreted scripting 
language”.
