JavaScript Transpiler

DWScript features a powerful Pascal-to-JavaScript compiler (dwsJSCodeGen). It allows you to write client-side logic in strongly-typed Object Pascal and deploy it as optimized JavaScript.

Key Features

Strong Typing: Catch errors at compile time before generating JS.
Smart Linking: The SmartLinker analyzes your code and removes unused classes, methods, and types from the final output, significantly reducing bundle size.
Optimizations: Loops, conditionals, and expressions are optimized for JS execution.
Source Maps: Debug your Pascal code directly in the browser.

Code Generation Options

Option	Description
`cgoSmartLink`	Enables the Smart Linker. Unreachable code is stripped.
`cgoObfuscate`	Minifies and obfuscates symbol names to protect intellectual property and reduce size.
`cgoPrettify`	Generates readable, indented JavaScript (useful for debugging).

Example

// Pascal Source
type
  TPoint = record x, y : Integer; end;

function Add(a, b : Integer) : Integer;
begin
  Result := a + b;
end;

// If "Add" is called, it will be in the JS output.
// If "TPoint" is unused, it will be removed by SmartLinker.

Libraries

Standard libraries like System, Math, and Classes are partially mapped to JS equivalents, allowing for seamless code sharing between server (native) and client (JS).
