Infinity (or -Infinity) is the value that JavaScript will return if a calculation yields a number beyond the maximum limit.
Example
| let myNumber = 2; // Execute until Infinity while (myNumber != Infinity) { myNumber = myNumber * myNumber; } |
Division by 0 (zero) likewise results in Infinity.
Example
| let x = 2 / 0; let y = –2 / 0; |
Infinity is categorized as a number; invoking typeof Infinity will yield “number“.
Example
| typeof Infinity; |
