在英语中,所有这些字符都被视为标点符号-
'!', "," ,"\'" ,";" ,"\"", ".", "-" ,"?"
我们需要编写一个JavaScript函数,该函数接受一个字符串并计算字符串中这些标点符号的出现次数并返回该计数。
让我们为该函数编写代码-
const str = "This, is a-sentence;.Is this a sentence?"; const countPunctuation = str => { const punct = "!,\;\.-?"; let count = 0; for(let i = 0; i < str.length; i++){ if(!punct.includes(str[i])){ continue; }; count++; }; return count; }; console.log(countPunctuation(str));
输出结果
控制台中的输出:-
