Q: What does JavaScript output when an infinite or definite value is encountered during an arithmetic computation in a programme?  

Answer: C

In JavaScript, if the result of an arithmetic operation is larger than the largest representable number,
the result will be positive infinity.
Similarly, if the result of an arithmetic operation is smaller than the smallest representable negative number,
the result will be negative infinity.
For example, consider the following code:

let x = 1.7976931348623157e+308;
let y = x * 2;
console.log(y); // prints "Infinity"

let a = -1.7976931348623157e+308;
let b = a * 2;
console.log(b); // prints "-Infinity"

In this example, the variables x and a are assigned the largest and smallest representable numbers, respectively.
When these numbers are multiplied by 2, the result is positive and negative infinity, respectively.
