lang/duktape 2.7.0 NetBSD

Duktape is an embeddable ECMAScript E5/E5.1 engine with a focus on portability and compact footprint. By integrating Duktape into your C/C++ program you can easily extend its functionality through scripting. You can also build the main control flow of your program in ECMAScript and use fast C code functions to do heavy lifting.

The terms ECMAScript and JavaScript are often considered more or less equivalent, although JavaScript and its variants are technically just one environment where the ECMAScript language is used. The line between the two is not very clear in practice: even non-browser ECMAScript environments often provide some browser-specific built-ins. Duktape is no exception, and provides the commonly used print() and alert() built-ins. Even so, we use the term ECMAScript throughout to refer to the language implemented by Duktape.
