Hi, I have decided to put to gather a document, logically thinking about a scripting language holistically on how to achieve type free scripting language that is consistent and predictable regardless of the data option which is operating. In other words, a script problem is type invariant and input and outputs will never differ base on any implicit, inferable, or backing types.
*Rules and constraint for writing a good scripting language or script for that matter, such that it has consistent predictable and usable behaviour* https://docs.google.com/document/d/1065G_MqNMFL_fBhSHSfH3ju0FUKC5iRpbj1iVwgAh3o/edit?usp=sharing Kind Regards, Wesley Oliver On Fri, Apr 10, 2020 at 3:33 PM Wesley Oliver <wesley.o...@gmail.com> wrote: > Hi, > > Just like to maybe challenge javascript here or any script language in > that mater. > > The definition of comparing two variables with an operator such as > <.<=,>,>= of the operators above definition changes depending on the left > and right backing types. > > If both are strings then it does string comparison if both numbers then > its numbers. > Seem great but there are small gotchas. > > So if someone writes an algorithm and some gives them some badly formatted > data, where some values are strings and some are numbers or what eva, > because we are operating in type free space. > Then sometimes the correct behaviour will be happening depending on what > the intention is. > string comparison or number comparison. > Some of the loops evaluate the data going to be doing all sort wonderfully > things, flipping between definitions. kinda works for sort single > numerical string sort method but not for logical algorithm comparisons, > because they may and much work from time to time depending on the input > data. > > Reason for a scripting language is be free of types and not care about > different types, that things just work, but clearly there some additional > corner cases, we need to improve on. > > The problem here is that based on the types the operator behaviour is > inconsistent. > To write script programs the behaviour for different operators needs to > remain the same > regardless of types.
