language: go
In this block of the .travis.yml script we add the programming language that we will be using in the continuous integration build. This is usually the first entry in the .travis.yml script that you add.
Travis CI supports many programming languages such as:
- C
- C++
- JavaScript with Node.js
- Elixir
- Go
- Haskell
- Ruby
You can look at languages (https://docs.travis-ci.com/user/languages) in the Travis CI docs for a complete list of supported programming languages.
