Hey everyone, Certificates.dev created this cool JavaScript Arrays cheatsheet in collaboration with Martin Ferret🧠

Hey everyone,

I got tired of juggling multiple bookmarks for simple tasks like formatting JSON, decoding JWTs, or converting Base64. So I built a single hub for all of them.

**What it includes:**

- JSON Formatter/Validator

- JWT Decoder & Visualizer

- Base64, URL, HTML Encoders/Decoders

- UUID Generator

- Regex Tester

- Color converters

- And 30+ more utilities

**Key points:**

- 100% client-side - nothing is sent to any server

- No sign-up, no ads, no tracking

I'd genuinely appreciate any feedback - what's missing? What could be improved? What tools do you use daily that I should add?

Thanks!

If you’re like me and often work with web content, finding the right editor can make a huge difference. After testing a few options, here are some tools I’ve found incredibly useful:

1. Froala – Great for basic text editing with minimal setup.

2. flexiclip– Has solid integration for media-rich content.

One tool I’m particularly impressed with is an editor from Froala. It’s been super customizable and has an intuitive, user-friendly interface. For projects where you need flexibility in design and responsive editing, it’s a strong option.

Just finished improving this interactive flight tracker that renders thousands of flights around a 3D Earth. The key breakthrough was implementing GPU instanced mesh rendering:

Performance Stats:

• 30,000+ aircraft: Single GPU draw call

• Instanced geometry batching for both planes and flight paths

• Custom GLSL shaders handle all animation on GPU

• ~1000x performance improvement over traditional rendering

• Consistent 60fps even with maximum flights

Tech Stack:

• Three.js + WebGL 2.0

• Custom vertex/fragment shaders

• Instanced mesh geometry

The GUI is organized into 5 control panels (Flight Controls, Flight Path, Plane Controls, Earth Controls, Brightness) for easy experimentation.

Would love feedback on the performance optimizations or any suggestions for improvements!

Boolean of console.log returns false . Any ideas why?

I used these two approaches to calculate the count value, but the first one resets the counter to zero .

To me both the statements looks the same yet assigning the variable 'counter' somehow doesn't reset the counter to zero.

Can someone please explain why?
