Issue with "Number.MIN_VALUE": Example is wrong

[MadaraUchiha]

MDN URL: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/MIN_VALUE

What information was incorrect, unhelpful, or incomplete?

function multiply(x, y) {
  if (x * y < Number.MIN_VALUE) {
    return 'Process as -Infinity';
  }
  return (x * y);
}

console.log(multiply(5e-324, 1));
// expected output: 5e-324

console.log(multiply(-1.7976931348623157e+308, 2));
// expected output: Process as -Infinity

The demo in question (at least the second one) seems copied from MAX_VALUE and a negative sign added. This is the wrong usage for MIN_VALUE (which is the closest positive value to 0, not the most negative number).

Specific section or headline?

Demo

What did you expect to see?

function divide(x, y) {
  if (x / y < Number.MIN_VALUE) {
    return 'Process as 0';
  }
  return (x / y);
}

console.log(divide(5e-324, 1));
// expected output: 5e-324

console.log(divide(5e-324, 2));
// expected output: Process as 0

Did you test this? If so, how?

I wanted to open a PR, but I didn't understand how to edit the example html file, and I couldn't find it in the project.

Hi! Nice catch.

I wanted to open a PR, but I didn't understand how to edit the example html file, and I couldn't find it in the project.

This is because, for historical reasons (we were a wiki before migrating to Github), the file is in a different repo.

Here is the file you are looking for:
