Are dynamic languages going to replace static languages? (2003)
&gt;   I can no longer concieve of writing software without using test driven development. I can&#x27;t imagine not having a comprehensive suite of unit tests to back up my development.<p>I&#x27;m the same with strong static typing. At its most basic, why would I give up getting the computer to automatically check for me at compile time that I&#x27;m passing the right number of parameters to a function, that a parameter is an array and not a string, a field can never be null, and that I haven&#x27;t made a typo in a variable name? Coding without these trivial checks of correctness feels archaic and backwards to me.<p>To make up for it in a dynamic language, you end up having to reimplement what a type checker would do for you with no guarantee you didn&#x27;t miss something or make a mistake, with the added cost of e.g. polluting your projects with noisy defensive code that double checks the types of parameters, adding extra tests, and bolting on linting, analysis and IDE tools to help.<p>I&#x27;m with the other posters too about the article content, if you haven&#x27;t coded in a language like OCaml, Haskell, ML etc. you really don&#x27;t know enough about what strong static types offer to discount them. Java, C and C++ have much weaker checks of correctness and lack type inference + pattern matching that make strong types pleasant to work with. The article says more about e.g. Java vs Python.<p>You want strong static types + tests, they&#x27;re not mutually exclusive at all but complementary.
