#5 Objective-C

Objective-C was created first by Brad Cox and Tom Love at their company Stepstone in the early 1980s. It is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. The language is now mostly used in Apple iOS and Mac OS X and is of great demand.

#4 JavaScript

JavaScript is an object-oriented scripting language that is smaller than Java. Being a client-side language, it runs in the web browser on the client-side with a simplified set of commands, easier code and no need for compilation. It is used in millions of web pages to authenticate forms, detect browsers and improve design. Some of the applications that contain JavaScript embedded codes include chrome extensions, Apple's Safari extensions, Adobe Acrobat Reader and Adobe's Creative Suite.
