// means comments. They are completely ignored in modern browsers.

There would be no change of speed. All your time difference measurement will be just due to the random white noise of your computer execution.

100x faster is undefined for 0ms

ChatGPT answer for your understanding:

---

Removing // comments in JavaScript does not improve performance at runtime because comments are not part of the code that gets executed by the JavaScript engine. Here's why:

1. Comments are ignored during parsing

When a JavaScript file is loaded:

• The engine (e.g., V8 in Chrome) parses the code.
• During this step, it skips over any comments (// or /* */).
• They are not converted into bytecode or executed in any way.

So once the code is parsed, comments do not exist anymore — they're simply discarded.

---

2. No runtime cost

Since comments are:

• Not stored in memory after parsing,
• Not processed during execution,

They add zero overhead during runtime — no CPU cycles, no memory usage, nothing.

---

3. When removing comments can matter

There are cases where removing comments helps, but they’re not about performance:

• Reducing file size for network transfer (important for web apps).
• This is usually done with minification (e.g., using tools like UglifyJS, Terser).
• Smaller files = faster loading, especially on slow connections.

However, once the code is downloaded and parsed, whether it had comments or not makes no difference to runtime performance.

---

Summary:

Removing // comments in JavaScript has no effect on execution performance, only potentially on file size and load times — and even that’s usually handled automatically by build tools.

WTF?!

I remove this trash! no just comments omg.
