Boot.dev vs. CodeSpace vs. JavaScript vs. Unlambda Comparison Chart

Easy to use browser-based software. Interactive curriculum modules, standards-based, project-driven learning. Physical computing-based robotics. Our unique learning platform brings together a powerful, open-ended coding environment, a teacher-friendly curriculum suite, and an exciting, thoroughly hackable set of hardware tools. CodeSpace helps you deliver real-world learning experiences to your students. Perfect for learning but industry-proven, Python has been used to develop software for Google, YouTube, Spotify, and countless other applications highly relevant to students' lives. Our exclusive use of text-based code, rather than drag and drop blocks, appeals to students seeking relevance, meaning, and real-world value from instruction. Our Python-based curriculum modules lead students (and teachers!) step by step, from basic coding concepts to deep and complex projects. Instructional content is integrated with development tools, so students can practice the mechanics of programming.

Unlambda is a programming language. Nothing remarkable there. The originality of Unlambda is that it stands as the unexpected intersection of two marginal families of languages. Functional programming languages, of which the canonical representative is Scheme (a Lisp dialect). This means that the basic object manipulated by the language (and indeed the only one as far as Unlambda is concerned) is the function. Rather, Unlambda uses a functional approach to programming: the only form of objects it manipulates are functions. Each function takes a function as an argument and returns a function. Apart from a binary “apply” operation, Unlambda provides several built-in functions (the most important ones being the K and S combinators). User-defined functions can be created, but not saved or named, because Unlambda does not have any variables.
