Contents
For nonprogrammers
Some of the best resources for somebody new to APL and programming in general are:
 APL Wiki's simple examples
 The Learn tab on TryAPL
 The book Mastering Dyalog APL by Bernard Legrand
 The APL Cultivation Stack Exchange Lessons
 The Zark APL Tutor
Follow one or a couple of these tutorials through and play around a bit. To learn APL the advice is similar to that for learning other languages: have a goal (something you want to accomplish) and try to do it. Along the way you are sure to come across the pitfalls and gotchas of the language, and with time you may come to understand what APL thinking means.
If you get stuck, don't hesitate to ask your questions in the APL Orchard chat room.
For nonAPL programmers
This is a list of tutorials and other resources of interest to someone who knows about programming or is familiar with another programming language, but wants to learn more about APL.
 APL Wiki's advanced examples
 APL Cultivation (chat lessons)
 TryAPL online interpreter with lessons
 Learn X in Y minutes
 Fear and Loathing with APL
 APL in 20 Minutes
 A Short Intro to APL
 Let's Learn A Programming Language
 APLWiki list of Books and Publications
 Mastering Dyalog APL
 GitHub repository
 Zark tutorial
 Trying APL
 Artificial Neural Networks
 FizzBuzz
For novice APLers
If you already have a fair grasp of APL's primitive functions and operators, you can sharpen your skills by challenging yourself with these:
 APL Crossword 5: Fill in expressions and snippets to fulfil all the clues.
 2016 Year Game: Find APL expressions involving exactly the digits 2 0 1 6 in that order to equal the numbers 0 to 100.
 2017 Code Golf Challenge: Find the shortest possible APL expression that evaluates 1…52 without using any number or character literals.
 APL Problem Solving Competitions — Try to solve past years' problems.
For old APLers
In the last decade, several implementations have extended APL with new primitives:
Primtives
Functions: ⊢
Same, Right;
⊣
Same, Left;
⌷
Materialise, Index;
≡
Depth, Match;
≢
Tally, Not Match;
⍸
Where, Interval Index;
⊆
Nest, Partition
Operators: ∘
Bind, Compose;
⍤
Rank;
⌸
Key;
⌺
Stencil;
⍠
Variant
Lambdas
Tacit programming
Dyalog APL documentation: Intro, Details
Other features
How to's for advanced APLers
