/**
 * 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 {any} value - The value to check if it is an object.
 * @returns {value is object} `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
