Why Programming Language :
For development of software
System Software and Application software are developed using various language ,reason is computer can understand only binary data
For human it is difficult to program in Binary, so there is a need of simpler language which human can work and which can be translated in computers language (Binary)
For the same reason there exist so many language like , C , C++ , Java ,Lua , JavaScript… etc.
Also , a lot of other language ,framework developed over the time to make it easier for work
