* 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 {any} value - The value to check
|
|
* @returns {boolean} `true` if `value` is integer, otherwise `false`.
|
|
*
|
|
* @example
|
|
* isInteger(3); // Returns: true
|
|
* isInteger(Infinity); // Returns: false
|
|
* isInteger('3'); // Returns: false
|
|
* isInteger([]); // Returns: false
