What is the difference between scripting language and programming language?

Question

I am little bit confused that why do we need scripting language. what is the purpose of scripting language and how it is different from any programming language.

Answer 1

Scripting lanugage is most often used in web development,
whereas programming language is most often used in app development.

Scripting language doesn't compile and execute but direct execute,
many Programming first compile/interprete and then execute.

Scripting language rendered on browser,
programming language needs a software like C++ needs a compiler, java needs jdk, python needs IDLE etc.
