If you want to do web browser then javascript For apple (IOS/OSX) then objective C or maybe Ruby or lua Embedded programming then C Microsoft you have a large choice C# or VB.Net perhaps Android is Java Enterprise programming then Java or C# Pose value haskell or scala :-) It depends on your background and what you want to do. I think every developer should know C or C++ but not as a starter unless you like serious hacking. Javascript is the language of the web browser so you'd need to know that for any browser programming. Enterprises run on C# or Java. Then of course there are all the scripting languages python is perhaps the most popular for general scripting, or powershell for windows
