         * `func` once it's called `n` or more times.

         * @since 0.1.0
      
         * @category Function
      
         * @param {number} n The number of calls before `func` is invoked.
      
         * @param {Function} func The function to restrict.
      
         * @returns {Function} Returns the new restricted function.
