Soo lets dicuss in the comments! 💪
JavaScript is Slow: JavaScript is still slow compared to the TOP 15 languages ranked in speed, JavaScript is still not in this list.
JavaScript is Untyped and Unsafe: TypeScript is typsafe, JavaScript isn't.
You Need jQuery to Manipulate the DOM: I'm not even a JavaScript developer and I know that no one ever said that.
JavaScript is Not Secure for Web Development: You shouldn't store API-Keys, Credentials or access database directly with your JS-Frontend. You still have to rely on real backends or frameworks.
Great points! 💡
JavaScript is slow – True compared to lower-level languages, but modern engines like V8 have made it much faster.
Untyped & Unsafe – JavaScript is dynamic, but TypeScript adds type safety for better reliability.
jQuery for DOM Manipulation –Agreed! Vanilla JS handles it just fine now.
Not Secure for Web Dev – Security depends on how it's used. Sensitive data should never be in the frontend.
Appreciate your insights! 🚀 What’s your take on JavaScript’s growth in backend dev?
*JavaScript is single thread so it's slow *
It's true, JavaScript is single thread language but it has the capabilities to handle tasks efficiently with it event manager system.
Today the part "single thread" language is half true because of the web workers which can handle processing tasks without blocking the web browser !
Let us get it straight here. JavaScript is untyped and unsafe. Typescript is typed and safe. Don't use JavaScript if you want to build serious and complex applications. Don't write as if Typescript is part of JavaScript.
Enough to use JSDoc to be safe.
Does JsDoc help you detect errors/bugs at build time? Does JsDoc prevent run time errors? Rather than combining Javascript with JsDoc for type safety, Isn't it better to use Typescript instead?

I appreciate your suggestion, but No, Thank you. I am more comfortable working with Typescript than JsDoc.
Very good points. I feel inspite of all these myths, JavaScript is lovely and has become very popular because of its versatility, simplicity, and expressiveness.
Using typeof to prove that JS primitives aren't objects are a bad way to do this, because you can access properties and methods of every primitive (with exception of null and undefined, these trully aren't objects), the thing is that, like Java, JS has boxing as a feature, so every primitive type is wrapped inside an object representing it, you can't really access an primitive in JS, because they're automatically boxed every time, so to all effects the phrase that everything is an object in JS is kinda true if we don't consider null or undefined.
