Application Development Utilities

An Error type and handlers for concise error handling for expected failure cases.

A very powerful script runner, JsShell, that's more precise and direct for controlled program executions than OS shells.

Since version 2.4.0 supports both CommonJS/ES5 requires and ES6 import...from. Since version 4.1.0 supports deno.
