Explanation by: Admin

In JavaScript, when an arithmetic computation results in an indefinite or infinite value, JavaScript does not throw an error. Instead, it returns Infinity (or -Infinity for negative values).

Example:

console.log(10 / 0);  // Output: Infinity

console.log(-10 / 0); // Output: -Infinity

If the result of a computation is undefined (like 0/0), JavaScript returns NaN (Not-a-Number):

console.log(0 / 0); // Output: NaN

Why Not Other Options?

  • (A) Prints the value as such → ❌ Incorrect (JavaScript does not print raw values; instead, it handles them specifically as Infinity).
  • (B) Prints an exception error → ❌ Incorrect (JavaScript does not throw an exception for division by zero).
  • (C) Prints an overflow error → ❌ Incorrect (JavaScript does not have an "overflow error" like some other languages).

Final Answer:

✅ (D) Displays “Infinity”
