Can anyone explain me about the basic purpose of scripting language in detail?

A scripting language is often defined as a programming language that doesn't require compilation to run. It's usually "compiled" by an interpreter or used by a virtual machine, e.g. PHP, Perl, Python, etc. This means the computer system has to process the code everytime it's accessed, although some languages will create a "compiled" version after the first run that it will then use.

Since I'm more familiar with Python right now, I'll explain how it works. Python has an interpreter that compiles the source code after the first run, creating a .pyc file from the original .py file. If the code doesn't change, then everytime the program is called, the Python interpreter will just use the .pyc file since it's already compiled. It will only use the .py file if the source code has changed.

Java does something similar to "normal" scripting languages in that it converts the source code into bytecode which is then ran via the Java Virtual Machine. This bytecode is OS independent, so you could pass the bytecode around as an "executable" version of the program.
