#Note Points
- Big companies choose C++ as their main language for back-end platform, like Google and Facebook and Yahoo and Amazon.
- Hot Start-up choose Python and Node.js.
- And PHP is still a good choice. Although currently people think that is old-fashioned, but if you dive into PHP, you will find something.
- Personally speaking, Python and C++ is a good combination.
