The examples below make use of the log function of the console object present in most browsers for standard text output. The JavaScript standard library lacks an official standard text output function (with the exception of document.write).
Boa is an open-source implementation of a JavaScript execution engine. The project is developed as a Rust library for embedding the JavaScript engine in Rust applications. Additionally, the authors of Boa provide a command-line interface (CLI) for users to interact with Boa as standalone JavaScript interpreter accessible from a command line. [8]
Polyfill (programming) In software development, a polyfill is code that implements a new standard feature of a deployment environment within an old version of that environment that does not natively support the feature.
