Less keywords is more

The go language is pretty cool. Coming back from a lot of python, it’s admittedly difficult to go back to compiling and static typing, sure. But it feels so much safer to know that your program can’t suddenly explode because some 3rd-party lib decided to return an int instead of a dictionnary.

There’s no while in go. Instead of while, you use for. Makes sense and we get rid of a keyword. Cool!

Another great thing is the if-with-initializer-statement. You can add a declaration statement to an if condition, e.G.

if isNeitherFizzNorBuzz := (len(accu) == 0); isNeitherFizzNorBuzz {
        accu += strconv.Itoa(number)

as opposed to e.G. python, where you’d use two statements instead :

is_neither_fizz_nor_buzz = not accu
if isNeitherFizzNorBuzz:
    accu = str(number)

The go version is totally readable because essentially to understand the if, you just need to read the first two words. if isNeitherFizzNorBuzz, that’s exactly what that thing does. This I like! You can extract the if condition in a variable without having to actually do it on a separate line. And it’s still readable.

Going a bit further, the if keyword has actually two uses, not unlike the for is used both for for-loops and for while-loops.

if err:= Function(); err!=nil{
    // TODO deal with error

That now requires to read 3 words but once again it’s straight to the point. “If err Function”, that’s exactly what it does. If the function errors, then do that.
