Jim Tcl — The Jim Interpreter is described as 'Jim is an opensource small-footprint implementation of the Tcl programming language. It implements a large subset of Tcl and adds new features like references with garbage collection, closures, built-in Object Oriented Programming system, Functional Programming commands' and is a programming language in the development category. There are more than 10 alternatives to Jim Tcl — The Jim Interpreter for a variety of platforms, including Mac, Windows, Linux, BSD and Web-based apps. The best Jim Tcl — The Jim Interpreter alternative is JavaScript, which is both free and Open Source. Other great apps like Jim Tcl — The Jim Interpreter are Lua, Tcl, Wren and Squirrel (programming language).
JavaScript (sometimes shortened to JS) is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but also used in many non-browser environments.
Lua is a powerful, fast, lightweight, embeddable scripting language.
Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode for a register-based.
Tcl (Tool Command Language) is a very powerful but easy to learn dynamic programming language, suitable for a very wide range of uses.
Squirrel is a high level imperative, object-oriented programming language, designed to be a light-weight scripting language that fits in the size, memory bandwidth, and real-time requirements of applications like video games.
The Bosque programming language is an experiment in regularized design for a machine assisted rapid and reliable software development lifecycle.
Wyvern is a new programming language designed to help developers be highly productive when writing high-assurance applications. The first major innovation in Wyvern is type-specific languages, a feature that allows programmers to create literals of a given type (e.g.
Chibi-Scheme is a very small library with no external dependencies intended for use as an extension and scripting language in C programs. In addition to support for lightweight VM-based threads, each VM itself runs in an isolated heap allowing multiple VMs to run simultaneously...
The AngelCode Scripting Library, or AngelScript as it is also known, is an extremely flexible cross-platform scripting library designed to allow applications to extend their functionality through external scripts.

JavaScript isn't a singular implementation. An actual alternative would be some JS engine (like V8, DukTape, JavaScriptCore).
