Learning JavaScript With Imagination — Smashing Magazine


This is the story of how one little octopus, explaining one beginner’s concept, carried such weight and power for Kylo that it drove his interest in visual learning and led him to research something that is really quite silly. And yet, it transformed how he learned to write — and finally understand — JavaScript.

Many years ago, I set my sights on becoming a senior developer. I achieved that goal! I wish I could say it was a matter of hard work and perseverance, but no, that wasn’t enough. JavaScript stood in my way, and it was while grappling with it that I came across one silly sentence in Marijn Habernecker’s classic book, Eloquent JavaScript. On the topic of variables, it says:

“You should imagine bindings as tentacles rather than boxes. They do not contain values; they grasp them — two bindings can refer to the same value.”

— Marijn Habernecker

An analogy like this falls into the category of childish comparisons meant mostly for raw beginners to understand basic concepts. They are fun and entertaining but not something that will turn you into a senior developer.

But it struck me. Even in a small way, this childish metaphor made me a better developer. It fixed a fundamental misunderstanding: we don’t put values in variables. If variables did behave like buckets or containers, how could this be true?

const count1 = 10; const count2 = count1;

How is it possible to have the same 10 value in two different buckets? The same thing can’t be in two places at the same...
