Phix is a self-hosted hybrid interpreter/compiler, developed by Pete Lomax. It is very easy to use, and similar to

On [https://rosettacode.org/wiki/Rosetta_Code/Rank_languages_by_popularity/Full_list?oldid=294533 26th December 2021, Phix became the first programming language on this site to have submissions for 100% of all tasks].<br>
A single 16MB download contains a pre-compiled executable, all the sources, and'' '''everything''' ''needed to recompile them, in about 15 seconds. The download also contains a full-featured programmer's editor and 130+ demo programs.▼

You can also [https://replit.com/@PeteLomax1/PhixInterpreter#main.sh run Phix on replit here] (1.0.3 Lnx 64 bit), and several manually transpiled and uploaded entries [https://rosettacode.org/wiki/Category:Phix/online here]
Perhaps the most striking feature of Phix is that it has just five builtin data types:
Line 26 ⟶ 32:
Despite such apparent simplicity, or perhaps precisely because of it, Phix programs are pretty fast - not quite achieving the runtime performance of C or assembly, but making up for it with a very fast edit/run cycle and proper human-readable messages should anything go wrong (even in shipped pre-compiled executables). Sequences are the real powerhouse of Phix. The one type covers lists, queues, tables, trees, and arrays, with strings being the subset that is array of character. They can grow and shrink automatically without any memory management overhead. For example if <tt>s="food"</tt> then <tt>s[2..3]="e"</tt> makes <tt>s</tt> "fed", and then <tt>s[2..1]="east"</tt> makes <tt>s</tt> "feasted".
Phix applies the principle of least surprise, for instance in some languages <tt>myproc(list)</tt> or <tt>res = myfunc(list)</tt> can mangle list, whereas in Phix if you actually want that to happen you would code <tt>list = myproc(list)</tt> (and myproc would need to become a function) or <tt>{res,list} = myfunc(list)</tt>. Likewise 1/2 is 0.5 (not 0, unless you explicitly ask for the floor()) and 0-1 is -1 (not +MAXINT). A core tenet is that for any line of code there is one and only one possible interpretation of it, and said meaning is utterly intuitive. True fact: the given answer for
Phix
Technically Phix does not have a garbage collector, instead it is reference counted, so memory is automatically reclaimed whenever a reference count drops to zero, and hence there are no sudden pauses, although the reference counting can itself reduce performance.
The fundamental goal of Phix is to make debugging easier, a whole subject area that does not seem to get the attention it deserves, despite several studies proving that all programmers actually spend between 70 and 90% of their time debugging. (Most of us tend to think that getting just-written code to work is somehow not debugging, but that bloke with a clipboard stood behind you would disagree.)▼

Since 1.0.0 you can also run (many/most) Phix programs in a browser, by using pwa/p2js (as included in the distro) to transpile the program to JavaScript (plus a bit of standard HTML and CSS). If you see "'''with javascript_semantics'''" it means the program has been tested and works fine, both on the (Windows/Linux) desktop/Phix and in a browser via pwa/p2js, and in fact unix_dict() has been added to avoid reading unixdict.txt. Conversely, "without js" being present on a rosettacode entry means that (for instance) it uses the local file system, and is therefore desktop/Phix only. It is worth pointing out that "with js" and deep_copy() have proved ''staggeringly'' effective and nowhere near as painful as first feared. In just a few months (1.0.0 was released in July 2021) I have tested, fixed where necessary, and marked as javascript compatible ''[https://rosettacode.org/w/index.php?search=phixonline&title=Special%3ASearch&wprov=acrw1 over 1,200 rosettacode entries]'' for Phix, and only ''[https://rosettacode.org/w/index.php?search=notonline&title=Special%3ASearch&wprov=acrw1 one seventh]'' of that have as yet been marked incompatible, despite things like file i/o being prohibited within a web browser. The [https://rosettacode.org/wiki/Category:Phix/online Phix/online] subcategory currently lists 99 entries deemed interesting enough to bother (manually) uploading to the Phix website (ping me should any stop working), and the next goal is to get pwa/p2js itself runnning online, but obviously without using file i/o directly. Another long term goal is to get Phix running on ARM, and since that would be utterly pointless without a viable GUI, I am currently elbow deep in writing a new cross-platform GUI, as a stepping stone (for both ARM and p2js/online).
