查找句子的平均单词长度-JavaScript
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存在的所有单词的平均长度,并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'));
输出结果
以下是控制台中的输出-
5.00 4.00
