Main Page

The information on these pages reflects many years of ongoing work on the development of the J programming language. We are committed to collecting this information carefully, presenting it clearly and accessibly, and continually refining it.

The J language is a high-level, general-purpose programming language with a unique and fascinating history. It has many distinctive features and serves as a powerful tool for developing algorithms and exploring problems that are not already well understood. J has many uses, but the predominant one is how it affects the way that you think about problems making you a better programmer.
