Ruby tutorial demystifies recursion with fibonacci: because who needs efficiency when you can watch your call stack explode like a bad pivot

Bennie van der Merwe, an electronic and software engineer, has published an article explaining recursion using the Fibonacci sequence with Ruby. The Fibonacci sequence is a mathematical concept where each number is the sum of the two preceding ones, often used to teach new programmers about recursion. Van der Merwe's article provides a simple recursive Ruby implementation and a tree-style explanation to help understand how recursive calls work. The example is intentionally simple and not efficient for large values, but effectively demonstrates how recursion breaks down a problem into smaller versions until a solvable case is reached. The article is republished from Medium for wider accessibility, aiming to educate new coders on recursion. With a clear and visual explanation, Van der Merwe's article serves as a valuable resource for programming education, highlighting the significance of recursion in software development and its applications in various industries, including technology and engineering.
