They are very different kind of languages and the way they handle exceptions might be rather different.. How is exception handling implemented and what are the implementation difference within these languages?
I am asking this question also because I noticed that C++ exception handling seems to be very slow compared to the JavaScript version.

Exception handling in java. Exception handling in C++ Only throwable objects can be thrown as objects. All types can be thrown as exception. In java, finally is a block that is executed after try catch block for cleaning up.
JavaScript is interpreted and sometimes compiled at runtime with a just-in-time (JIT) compiler. C is statically typed. JavaScript is dynamically typed. C requires programmers to allocate and reclaim blocks of memory.
Key differences between Java and JavaScript: Java is an OOP programming language while Java Script is an OOP scripting language. Java creates applications that run in a virtual machine or browser while JavaScript code is run on a browser only. Java code needs to be compiled while JavaScript code are all in text.
