PHP also has a nice thing I wish more languages had, which stops you shooting yourself in the foot due to this - the concatentaion operator (.) is different fro

  I can't think offhand of a language that does overload + for strings by default. Perl uses . Oracle SQL uses || Microsoft SQL and VBA use & C obviously doesn't use +. Neither does Pascal. Power Query doesn't.

    JavaScript, Python, Ruby, Go all use +.
  • Frondo 5y ago
    C# does, as do quite a few others. Heh, this is kind of interesting: https://www.rosettacode.org/wiki/String_concatenation https://www.rosettacode.org/wiki/String_concatenation

    C#, GoLang, Javascript, Python, and Ruby are several. Python and Ruby even overload *, for the dubiously useful construction: "hello" * 3 == "hellohellohello"

      I like Julia's standard string concat which subverts a Python user's intuition: "string1" * "string2" == "string1string2". Why? Because monad.
  • dahfizz 5y ago
    Java and Python, from the top of my head, allow "str1" + "str2"

      >Nope, Microsoft SQL uses +. I was referring to Access. >Original Pascal didn't, but I think most modern Pascals do I'm pretty sure concat() was used in THINK and Metrowerks Pascal in the 90s.

    Pascal does, at least in all the more common dialects. VBA (and VB in general) overloads "+" for strings in addition to providing "&", the difference being mostly in what gets converted to what in various situations: https://docs.microsoft.com/en-us/office/vba/language/reference/user-interface-help/plus-operator#remarks https://docs.microsoft.com/en-us/office/vba/language/referen...
    • perl4ever 5y ago
      Is there any reason anyone in their right mind would use + that way in VBA?
      • int_19h 5y ago
        I've seen plenty of code in VBA and VB6 that does so. I think it stems mostly from & being a late addition to BASIC (earlier BASICs only had +).
• coding123 5y ago
  The reason other languages don't have that is very few languages will implicitly convert that "5" to a number. Instead other languages generally only have the implicit convert to string as it's considered less magical.
