我们需要编写一个 JavaScript 函数，该函数接受由空格连接的字符串。该函数应计算并返回字符串中所有单词的平均长度(四舍五入到小数点后两位)

示例

以下是代码 −

const str = 'This sentence will be used to calculate average word length';
const averageWordLength = str => {
   if(!str.includes(' ')){
      return str.length;
   };
   const { length: strLen } = str;
   const { length: numWords } = str.split(' ');
   const average = (strLen - numWords + 1) / numWords;
   return average.toFixed(2);
};
console.log(averageWordLength(str));
console.log(averageWordLength('test test'));
