So I study programming languages from professional programmers through some program that is paid by the government(right now I mainly know python and c but next year I will learn c++ too)

but I want to learn even more so I chose to learn javascript with my friend during the summer(and of course continue to learn it after it). so anyway I was wondering if someone has any good courses to recommend on? I know there are a lot of them out there but I wanna make sure we learn from something good and not learn as good as we can. so if anyone has any good courses to recommend on it will be really nice :) both I and my friend are not familiar with javascript but we have knowledge of other subjects and languages.

Hi everyone,

I’m a UX preparing a short introductory UX session for a group of full‑stack developer students (HTML/CSS/JS, React, Node, Mongo, a bit of WordPress, Git, etc.). I will give them just a few hours of UX to help them in real projects and jobs, not turn them into designers.

So, I'm curious, for those of you who are developers:

• If you only had 2–4 hours of UX training, what would you actually have wanted to learn?

Thank's!

Hey! Have you ever learned a concept (or some) in JavaScript or Vue that made the whole its picture clearer to you, explained many things about the language and just advanced you? Like a 'wish-I-learned-that-sooner' thing!

There are many more wonderful things like template literals or classList I think. And I remember that when I was much younger, I had fun with random scenarios based on Math.random()

Quick tip for anyone working with JavaScript (frontend or Node):
Most of us think JS doesn’t handle memory well. I did too — until I learned how it actually manages memory.

Key takeaways:

• How stack vs heap works

• What reachability means

• Why the Mark-and-Sweep algorithm matters

• Why circular refs don’t necessarily cause leaks

• Common patterns that cause real leaks (timers, event listeners, global refs)

Ever used .sort() without a callback and thought it “just works”?

Well… sometimes it does. Sometimes it doesn’t. 😅

Let’s look at this 👇

💬 Key takeaway:
sort() without a callback converts items to strings and compares their Unicode order.

To sort objects properly, always pass a comparator.

Next time you see .sort(), ask yourself —

👉 “Is JavaScript sorting what I think it’s sorting?”

Feedback, questions, or discussions are more than welcome. Let’s talk JavaScript! 💬

I'm noob in programming, but I need it for my romanization project, and that work good with one letter changing, but I need to change firstly the "жё - žo", and after that "ж - ž" Please help, if you can

what will be the answer>?

**1.**console.log(10n+2);

**2.**console.log( !{} && someFunction() );

**3.**console.log( !-0 + !!Infinity + !null + !!undefined);

Ever noticed this in JavaScript?

console.log(-50 * 0); // Output: -0

At first glance, it seems odd—shouldn't -0 just be 0? But JavaScript (and many other languages following IEEE 754 floating-point arithmetic) distinguishes between 0 and -0.

Why does this happen?

Negative numbers retain their sign even when multiplied by 0.

IEEE 754 representation allows -0 to exist separately from 0.

While -0 === 0 is true, certain operations like 1 / -0 result in -Infinity.

It's one of those quirks that rarely matters but is fun to know!

Have you encountered a scenario where -0 caused unexpected behavior?

I've been playing around with nested functions in JavaScript and wanted to share an example to explain how data flows between functions. Here's a simple scenario involving a fruitProcessor function that uses another function, cutFruitPieces, to first cut fruits into pieces before making juice.

Here's the code for the cutFruitPieces function that simply multiplies the number of fruits by 4, assuming it cuts each fruit into 4 pieces:

javascriptCopyEditfunction cutFruitPieces(fruit) {
  return fruit * 4;
}

Now, let's look at the fruitProcessor function. It receives a number of apples and oranges, uses cutFruitPieces to cut them into pieces, and then creates a juice string:

javascriptCopyEditfunction fruitProcessor(apples, oranges) {
  const applesPieces = cutFruitPieces(apples);
  const orangesPieces = cutFruitPieces(oranges);
  const juice = `Juice with ${applesPieces} apple pieces and ${orangesPieces} orange pieces.`;
  return juice;
}

When you call fruitProcessor(2,3), here's what happens:

• fruitProcessor is called with 2 apples and 3 oranges.

• Inside fruitProcessor, cutFruitPieces is called for both apples and oranges, turning them into 8 apple pieces and 12 orange pieces, respectively.

• It then returns "Juice with 8 apple pieces and 12 orange pieces."

To see this in action, you can simply log the result to the console:

javascriptCopyEditconsole.log(fruitProcessor(2,3));

This outputs: "Juice with 8 apple pieces and 12 orange pieces."

Discussion: This example demonstrates how you can call one function from inside another to manipulate data before further processing. One might ask why not just multiply the input values by 4 directly within fruitProcessor? Well, using a separate function like cutFruitPieces can be helpful for keeping your code modular and easier to manage, especially when the logic for cutting fruit becomes more complex.
