The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
Go was designed at Google in 2007 to improve programming productivity in an era of multicore, networked machines and large codebases. [23] The designers wanted to address criticisms of other languages in use at Google, but keep their useful characteristics: [24]
