In this Lisp for beginners course, @the-lisper will teach you why this elegant programming language has influenced computer science for over 60 years. Lisp's elegant approach to handling code as data, combined with its powerful macro system and functional programming paradigms, offers developers unique insights into program architecture that remain relevant and influential across modern languages like Python, JavaScript, and Rust. ❤️ Support for this channel comes from our friends at Scrimba – the coding platform that's reinvented interactive learning: https://scrimba.com/freecodecamp ⭐️ Contents ⭐️ - 0:00:00 Common Lisp #1 - Installation - 0:06:45 Common Lisp #2 - Playing with the REPL - 0:13:04 Common Lisp #3 - Local variables and branching - 0:28:42 Common Lisp #4 - Looping with dotimes and do - 0:39:17 Common Lisp #5 - What are lists? - 0:48:47 Common Lisp: 4 ways to build lists - 0:56:28 Common Lisp: Introduction to macros (for beginners) - 1:08:10 Common lisp: macro vs functions (for beginners) - 1:18:00 Common LISP: Destructuring and more! - 1:24:23 Getting started with packages in Common LISP - 1:32:00 Prevent Macro Name Conflict with (gensym) - 1:36:32 Mastering Inheritance and Polymorphism with CLOS: An Introduction - 1:42:12 Mastering Inheritance and Polymorphism with CLOS: Multi-methods - 1:47:21 Common Lisp Debugging: Essential Tips and Techniques - 1:54:51 Exploring the Condition System of Common Lisp - 2:04:53 Mastering Built-in Types in Common Lisp (or how I got 3x faster execution with the same algorithm) - 2:13:13 Improve Common Lisp Code Clarity With Better Dictionary Literal - 2:21:30 Manual Memory Management in Common Lisp with CFFI - 2:28:29 Closures in Common Lisp, when CLOS Is Too Much - 2:36:08 Tail Recursion With Common Lisp, Do or Don't? - 2:41:08 Common Lisp: defvar vs defparameter - 2:46:45 Series: A Functional Approach To Common Lisp - 2:52:40 Haskell-Like Type System In Common Lisp With Coalton - 2:59:14 The Loop Macro in Common Lisp: Not Lispy but Convenient - 3:06:58 Circular list with Common Lisp 🎉 Thanks to our Champion and Sponsor supporters: 👾 Drake Milly 👾 Ulises Moralez 👾 Goddard Tan 👾 David MG 👾 Matthew Springman 👾 Claudio 👾 Oscar R. 👾 jedi-or-sith 👾 Nattira Maneerat 👾 Justin Hual -- Learn to code for free and get a developer job: https://www.freecodecamp.org Read hundreds of articles on programming: https://freecodecamp.org/news

This is CS50, Harvard University’s introduction to the intellectual enterprises of computer science and the art of programming, for concentrators and non-concentrators alike, with or without prior programming experience. (Two thirds of CS50 students have never taken CS before.) This course teaches you how to solve problems, both with and without code, with an emphasis on correctness, design, and style. Topics include computational thinking, abstraction, algorithms, data structures, and computer science more generally. Problem sets inspired by the arts, humanities, social sciences, and sciences. More than teach you how to program in one language, this course teaches you how to program fundamentally and how to teach yourself new languages ultimately. The course starts with a traditional but omnipresent language called C that underlies today’s newer languages, via which you’ll learn not only about functions, variables, conditionals, loops, and more, but also about how computers themselves work underneath the hood, memory and all. The course then transitions to Python, a higher-level language that you’ll understand all the more because of C. Toward term’s end, the course introduces SQL, via which you can store data in databases, along with HTML, CSS, and JavaScript, via which you can create web and mobile apps alike. Course culminates in a final project.

In this series, we'll learn AdonisJS 6 step-by-step in a beginner-friendly way. Covering topics like routing, controllers, services, EdgeJS, Lucid ORM, forms, filtering, authentication, etc.
