🧛♂️ 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.

⛳️ 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
