Is J good?
J is a powerful, high-performance array programming language descended from APL, well-suited for those who value extreme conciseness, mathematical elegance, and speed in numerical and data-processing tasks, though its terse syntax presents a steep learning curve.
Why choose J?
- Extremely concise syntax that allows complex operations to be expressed in very few characters
- Array-oriented design makes it exceptionally efficient for vectorized and mathematical computations
- Free and open-source with active community support and documentation
- Fast execution due to its low-level, optimized interpreter
- Rich built-in library for statistics, linear algebra, and data manipulation
- Cross-platform availability (Windows, macOS, Linux)
- Encourages a unique problem-solving mindset that can improve algorithmic thinking
Recommended for
- Mathematicians and statisticians needing rapid prototyping of numerical algorithms
- Data scientists working with large array or matrix computations
- Enthusiasts of APL-family languages looking for a modern, refined alternative
- Computer science educators teaching array programming concepts
- Competitive programmers who enjoy concise code golf-style solutions
- Researchers requiring high-performance computation without heavy language overhead

Check the traffic stats of J on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
-
Check the "Domain Rating" of J on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of J's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
-
Check the "Domain Authority" of J on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.

How do you Programm with esoteric languages?
Does J count a "esoteric"? If so, I do directly write J code, interactively. It's often a sort of exploration, a dialogue with the interpreter. J's conciseness makes that quite pleasant. Source: over 2 years ago

I Completed All 8 Advents of Code in One Go: Here Are the Lessons I Learned.
Sure. Advent_of_Code (AoC) is a computer programming competition thatโs been running since 2015. Problems are released daily from 1 December for 24 days. Thatโs the Advent thing. Each registrant gets their own data and has to write a program that produces a matching solution unique to their data usually a single number. You get a star if you get the correct answer. There is a ranking based on how long from release... Source: over 3 years ago

Solving Wordle with APL
I started learning APL in 1974 and J about twenty years later. I think youโll find J (https://jsoftware.com) will be easy to pickup. You have the APL idioms down pat. I have to relearn them as I donโt use either much these days. Source: over 4 years ago

Array programming language(s) for 3d-graphics?
I like J, from jsoftware.com. They came up with a genius way of representing all primitives with ascii characters combined with periods or colons (a couple of exceptions). If you download and install, go to the demos and labs to see 3D graphic implementations and all sorts of other examples of capabilities. Source: almost 5 years ago
