* Checks if `value` is an integer.

* This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to `number`.
*
* @param value - The value to check
* @returns `true` if `value` is integer, otherwise `false`.
*
* @example
* isInteger(3); // Returns: true
* isInteger(Infinity); // Returns: false
* isInteger('3'); // Returns: false
* isInteger([]); // Returns: false
