JavaScript: Loved, Hated and Ubiquitous

😄 JavaScript: Loved, Hated… and Somehow Everywhere. “This is my favorite language.” 👉 points at JavaScript Then reality kicks in: "11" + 1  // "111" "11" - 1  // 10 Welcome to JavaScript type coercion — confusing, powerful, and strangely fascinating. 💡 This meme perfectly explains why JavaScript sparks endless debates: • It’s flexible ⚡ • It’s unpredictable 😅 • It’s everywhere 🌍 From frontend frameworks like React, Vue, Angular to backend runtimes like Node.js, and even mobile & desktop apps — JavaScript dominates the modern stack. 🔍 But here’s the real lesson (and it’s not “JavaScript is bad”): Every programming language has quirks. Great developers learn how to work with them — not complain about them. 🎯 What actually matters: ✔ Understanding why behavior happens ✔ Writing clean, predictable code ✔ Knowing when (and when not) to use a language ✔ Mastering fundamentals: types, scope, execution context Memes are fun. But deep understanding is what makes you professional. JavaScript doesn’t make you weak. Not understanding it does.

We appreciate the shout out!

It's made on the common sense!! + You are not adding your are concatenating on the current value - doesn't have anything to relate with string so it behaves like that. Simple!!

Javascript: console.log(typeof NaN === "number"); // NaN means Not-A-Number but its type is still number Console: true

My least favorite language is Progress.

+ has multiple meanings (add, concat) - has not That's why. In C++, you may override the last operator if you want. But would it make sense?

The reason is pretty simple. And makes sense if you think about it. The + operator works on strings, so it concatenation the strings. The - operator does not work with strings, so Js converts them to numbers and does the operation.

Have used JS my whole career and hated it until I read https://share.google/FSGnOCDrsH1dSDd4z which explains a lot of these quirks.

people hated on php for using "." for concatenation, imagine JS having a different operator for concatenation, how many bugs and memes would have not been created

I recommend refreshing your understanding of what the ‘+’ and ‘–’ operators actually do.
