+/**
+ * Checks if the given value is boolean.
+ *
+ * This function tests whether the provided value is strictly `boolean`.
+ * It returns `true` if the value is `boolean`, and `false` otherwise.
+ *
+ * This function can also serve as a type predicate in TypeScript, narrowing the type of the argument to `boolean`.
+ *
+ * @param {unknown} x - The Value to test if it is boolean.
+ * @returns {x is boolean} True if the value is boolean, false otherwise.
+ *
+ * @example
+ *
+ * const value1 = true;
+ * const value2 = 0;
+ * const value3 = 'abc';
+ *
+ * console.log(isBoolean(value1)); // true
+ * console.log(isBoolean(value2)); // false
+ * console.log(isBoolean(value3)); // false
+ *
