.jsk

.jsk is a small JavaScript-inspired programming language implemented in modern Node.js with ES Modules. It uses a lexer → parser → AST → interpreter → runtime architecture.

Install

From the project directory:

npm install
npm link

No third-party dependencies are required.

Run

jsk file.jsk

Syntax

Variables

factor name = "World";
factor age = 20;

factor is the .jsk declaration keyword corresponding to JavaScript-style variables.

Functions

undef greet(name) {
  printWrd("Hello " + name);
}

greet("World");

Classes

Classes use grade and methods use undef:

grade Person {
  undef init(name) {
    printWrd(name);
  }
}

printWrd

printWrd("Hello World");

if / else

A single = inside an if condition is treated as equality comparison by the .jsk grammar:

factor name = "text";

if name = "text" {
  printWrd("hi");
} else {
  printWrd("bye");
}

try / else

try (
  printWrd(unknown);
) else (
  printWrd("An error occurred");
)

This maps conceptually to JavaScript try/catch.

HTML system API

.jsk provides system.createElement(), dynamic system.<elementName>(), and finishElement():

factor cds = system.createElement("cds") {
  systemType: "code";
  systemLanguageType: "html";
}

finishElement();

system.cds({
  <h1>contoh</h1>
});

The runtime keeps named system elements and can render their content as HTML. The lexer/parser also preserve the ordinary .jsk grammar around the API.
