Quick Demo
Here’s what it does to a function like this:
function area(a, b) {
console.log("I will find area of rectangle whose length and width are", a, b);
console.log("area of rectangle is", a * b);
return a * b;
}
After CodeCharm:
function area(a, b) { // Function to calculate area 👍
console.log("I will find area of rectangle whose length and width are", a, b); // Log input values 📏
console.log("area of rectangle is", a * b); // Calculate and log area 📐
return a * b; // Return calculated area 💯
}

Why I Built It
Sometimes I just wanted quick, clear comments for my code — not novels.And if you’re someone who loves both code and clarity (with a side of emojis), CodeCharm is your new favorite dev tool.
I built this extension for myself, but if it helps even one more dev write cleaner code faster — it’s all worth it.
