lu: ????????
I've decided to continue learning J. I had months ago heard about it somewhere, then forgot or got up to other stuff, among other excuses. Installation via instructions provided in the wiki to access newest version. There exists an IDE called JQt. It runs on Android, ARM, iOS, GNU/Linux, Windows. Resources include:
wget: , but insignificantly so for the non-advanced, also the language is (mostly) backward-compatibleAlternative attempts will be enumerated in comments; fixmes indicate incomplete problems and or unsatisfactory solutions. If your teeny-tiny brain can't handle opening and reading one of the above, I've written a small introduction.
NB. is an initialism of the Latin 'nota bene', meaning 'note well', and it is used to start a comment, continuing until end of line. I am unaware whether it is a part of sentence, a control structure, or something else. J's REPL uses an indentation of 3 spaces for user input, which I'll use here only. Computation results are without. Lastly, along with all the other Iversonian array programming languages (for a comparison of some languages' features, see here, or check out each language's wiki or documentation: APL, BQN, Kx, K6unofficial, K3unofficial, Nial, Uiua), J parses: 1, from right to left; 2, without operator precedence, though parentheses take precedence (and I'll be using these to either explicate tacit code, to emphasise, or because necessitated); and, 3, usually greedily (read more about parsing in the J wiki, which PoS gobble such).
- / 1 2 3 4 NB. = 1 - 2 - 3 - 4 = 1 - (2 - (3 - 4))
_2
11 * 0 + 3 NB. = 11 * (0 + 3)
33
Lastly, to forgo umpteen resolves-tos and equals, I'll use the J dyadic primitive for 'match' (or exact copy; it takes shapes into account) '-:', which returns 0, false, or 1, true, to denote equality in value, parsing, result, or something else. I'll be giving examples of the PoS or concept and or of their usage.

A noun (N) is a constant, a literal, an object, usually mathematical one: ±∞, NaN (indeterminate), numerals or numerics (booleans, reals, rationals, complexes, numeral of a base (any of), pi-based, radian-based, degree-based), strings (char array, though there is extended precision to UTF-4 and UTF-8, and with the unicode primitive 'u:'), boxes (a container type), all of any shape (a list (a 1-dimensional array) of non-negative values, roughly corresponding to something like a reduced matrix' column, row, and so on ranks, in a predefined order, always starting from row (because J is [row-major](https://en.wikipedia.org/wiki/Row-_and_column-major_order), not all Iversonian or array programming languages are!)) or nestedness (boxes in boxes in ...), in addition the a special kind called a symbol, which is like a boxed string, but with special properties. All these are either scalars or arrays. The first haven't a shape (J has decided that shape of '0', or '0 0 0 ...' does not a scalar make, and I agree based on how I think of spaces. These despite their 0 length in each dimension or along each axis, exist in an #@\$-dimensional space.), the second do. The canonical left and right nominal arguments that are acted upon in definitions, covered later, are x and y.

A verb (V) is like a function in that it does something to something, that is, a noun. In J, verbs are 'monadic', 'dyadic', or 'nulladic' (words referring their arity, the number of arguments they accept; here, 1, 2, 0), depending on the primitive, or your V-definition.

An adverb (A) is a first-order higher 'function'. It modifies its left word or phrase to produce a derived entity, most often a verb. The verb or noun operand is canonically called u or m. In the common case, V' -: (V A). They're also commonly written without a separating space, even by clean coding veterans, which is how I'll proceed.
i. 3
0 1 2

_ (1 2) } i.4 NB. amend, 'x m} y' amends y by creating a new noun that is a copy of y with the locations m replaced by new values x; very inefficient bc. not in place
0 _ _ 3
A conjunction (C) is a second-, third-, or fourth-order higher 'function', taking 2⸺4 PoS, argumentwise, and, doing something to or with those, can yield any PoS. The verb and noun to the right are canonically named v and n.
((+ & 2) ^: _1) 7 NB. ^: applies the left V and the right N times; negative reverse
5
(2 & ^ , ^ & 2) 3 NB. & binds a dyadic V's x or y, creating a monad; beware greediness
8 9
(7 8 9 &+ &. |.) 10 * i. 3 NB. 'under' applies v, then u, then the inverse of v to y (and x); not 3 7 11
19 28 37
(2&* @ 10&-) 3 NB. @, @:, &, and &: compose verbs, rank- and action-wise they differ slightly, but significantly

A train is a sequence of PoS, which combine to a(nother) PoS. Linguistically, this makes no sense, afaik.
A hook is a V-only one, sometimes called a 2-train. V1 preprosseses y, before handing it off V2, which is dyadic, and, which in absense of an x, copies the original y as the other operand. That is, (x V2 (V1 y)) -: (x (V1 V2) y), and (y V2 (V1 y)) -: ((V2 V1) y).
(2&* 1&+) 3 NB. add 1 from the right, then multiply by 2 from the right (and by self or x)
32
(* *) _10 0 20 NB. multiply by sign, a crude absolute verb (opposite monadic primitive, |), which doesn't gel with complex numerals
10 0 20
A reverse hook operates similarly but in opposite direction, preprosessing with V2 and dyadically using V1. BQN has a primitive for this, whereas J doesn't. However, we can define one using definitions' left and right V:
+ {{v u}} -
- +
A fork is the second type of V train, also called a 3-train. ((v3 X) v2 (v1 Y)) -: (X (v3 v2 v1) Y) AND ((v3 Y) v2 (v1 Y)) -: ((v3 v2 v1) Y). V trains of more than 3 (or resolved PoS) alternate from the right to the left between hooks and forks: (V4 (V3 V2 V1)) is a hook with a preprosessing fork. Additionally, if you wish V2 to be monadic, you may use '[:', called cap, for the first tine of the fork.
(2&* , 2&%) 4

Assignment is done globally with =:, and locally with =.. Direct definitions of any PoS use {{...}} and are less of an eyesore than the dyadic define verb : , where x is the 0, 1, 2, 3, 4 for noun, adverb, conjunction, monadic verb, dyadic verb. Beware, the space before the colon is necessary (because of constant functions matching the regex '_?\d:', which return a number).
