FastScript vs. JSDefender vs. Lua vs. PureScript Comparison Chart

FastScript is a cross-platform, multi-language scripting engine. It is useful for programmers who want to add scripting ability to their projects. FastScript can be used in Delphi 7-XE8, C++Builder 2005-XE8, Embarcadero RAD Studio 11 and Lazarus. FastScript is written entirely in 100% Object Pascal. A unique feature of FastScript is its ability to use several languages (PascalScript, C++Script, BasicScript, and JScript). This allows you to write scripts using your favorite language. FastScript does not use the Microsoft Scripting Host so it can be used in both the Windows and Linux environments and also in Mac OS. FastScript offers a wide range of features, including cross-platform scripting, fast code execution, a small footprint, a large variety of tools, and excellent scaling options. Use FastScript to make your applications really flexible and powerful!

Lua is a powerful, efficient, lightweight, embeddable scripting language. It supports procedural programming, object-oriented programming, functional programming, data-driven programming, and data description. 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 with a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping. Lua has a deserved reputation for performance. To claim to be "as fast as Lua" is an aspiration of other scripting languages. Several benchmarks show Lua as the fastest language in the realm of interpreted scripting languages. Lua is fast not only in fine-tuned benchmark programs, but in real life too. Substantial fractions of large applications have been written in Lua.
