🧛♂️ Common Causes of Memory Leaks in JavaScript
Identify and fix common JavaScript memory leaks (Node.js and Deno.js)
Memory leaks are a silent threat that gradually degrades performance, leads to crashes, and increases operational costs. Unlike obvious bugs, memory leaks are often subtle and difficult to spot until they start causing serious problems.
Increased memory usage drives up server costs and negatively impacts user experience. Understanding how memory leaks occur is the first step in addressing them.

CSS Transitions are the easiest way to add interactions on the web; all you need is an element in two different states with the transition property applied to its initial state, and the browser will smoothly animate the element between these two states.

🤯 Do you know this GitHub hack?
1️⃣ Open any GitHub repository
2️⃣ Replace .com with .dev
3️⃣ View the repository code in a VS Code instance!
And yes, you can just press the "." button on your keyboard.

⛳️ Cleave.js has a simple purpose: to help you format input text content automatically.
The idea is to provide an easy way to increase input field readability by formatting your typed data. By using this library, you won't need to write any mind-blowing regular expressions or mask patterns to format input text.
However, this isn't meant to replace any validation or mask library, you should still sanitize and validate your data in backend.

😳 In Your Face
VSCode extension that reacts to errors in code. And it is not just anyone who reacts to your errors, but the face of the main character of the legendary DOOM, from the times of DOS and Windows 95
Every time an error is detected in the code, the extension displays the corresponding "Ouch Face", which makes the debugging process more interactive and fun

🍐 Interview Question
What is a closure in JavaScript and how does it work?
A closure is a combination of a function that retains access to variables from its outer scope, even after the outer function has finished executing.
1️⃣ Context Memorization:
When a function is created, it remembers all the variables in its scope. These variables are available to the function even after the outer function has finished executing.
2️⃣ Private Variables:
Closures allow you to create private variables that cannot be changed or seen outside the function. This makes your code safer and more organized.
3️⃣ Persistent Data:
Closures allow functions to retain state between calls. For example, counters or cached values.
4️⃣ Asynchronous Operations:
Closures are often used in asynchronous code to preserve access to variables from the outer context while performing asynchronous tasks, such as timers or queries.
