/**
* Checks if the given value is an object. An object is a value that is
* not a primitive type (string, number, boolean, symbol, null, or undefined).
*
* This function tests whether the provided value is an object or not.
* It returns `true` if the value is an object, and `false` otherwise.
*
* This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to an object value.
*
* @param value - The value to check if it is an object.
* @returns `true` if the value is an object, `false` otherwise.
*
* @example
* const value1 = {};
* const value2 = [1, 2, 3];
* const value3 = () => {};
* const value4 = null;
*
* console.log(isObject(value1)); // true
* console.log(isObject(value2)); // true
* console.log(isObject(value3)); // true
* console.log(isObject(value4)); // false
