 As for programming precedent, stack-based languages such as Forth go from left to right. In Java-style object-oriented programming, methods go from left to right. This style of "method chaining" is particularly prevalent in Javascript.
 
 - There's an [APL Wiki category](https://aplwiki.com/wiki/Category:Left_to_right) that gathers some left-to-right languages. [Jelly](https://github.com/DennisMitchell/jellylanguage) is likely the most widely used of these, but being a code golfing language it's explicitly designed for brevity first and usability second.
-- [xs](https://github.com/smabie/xs) is a concatenative (or stack-based) array language not yet on APL Wiki.
 - Milan Lajtoš is working on the Fluent language for his "new kind of paper". Its LtR nature is mentioned in [this post](https://mlajtos.mu/posts/new-kind-of-paper-2).

 <p>English text is read left to right. This in itself is not decisive in either direction: many contend that the way to read a function is first to read the function, then its argument. Although I usually read the other way, I do find that order to be useful sometimes.</p>
