J vs V

3 classes of operators (verbs, adverbs, and conjunctions) with verbs the most basic function that take either 1 or 2 (infix) parameters. Operators allow function composition with a minimum of parentheses.

J also supports multiline functional definitions similar to BASIC/Pascal. Including error handling.

Each built in operator is a C/asm function, and special code further optimizes some operator combinations. Result is optimized C speed from quick parsing. Array orientation parses and compiles a function once, and applies it to all array items.

Still actively developed, but most recent changes have been in libraries and IDE and platform support.
Language is considered "perfected"... though not quite.

Complete core programming functional tools allow writting programs and libraries without imports.

(... within each of the 3 operator classes) makes reading code easier. Very simple parsing rules.

V is easier than C and fast like C.

Can import C libraries, structs, and headers.

Compile to many OSes.

V is simple and powerful.

Multi-OS GUI creation is more integrated into the language than others.

Highly understandable language.

V has Sum Types.

V has generics.

V has closures, which gives the user additional options and usefulness.

V is very safe.

Follows the philosophy that there should be only one way to do something, as opposed to multi-paradigm languages like C++.

Can run functions concurrently that communicate over channels.

Compiles programs fast, less waiting around, so more productive and fun.

Just check the V Discord channel or their GitHub Discussions and you will see by yourself.

Can add Assembly code.
