计算元音，辅音的出现-JavaScript
我们需要编写一个JavaScript函数，该函数接受包含英文字母的字符串，例如-
const str = 'This is a sample string, will be used to collect some data';
该函数应返回一个对象，该对象包含字符串中元音和辅音的数量，即输出应为-
{ vowels: 17, consonants: 29 }示例
以下是代码-
const str = 'This is a sample string, will be used to collect some data';
const countAlpha = str => {
return str.split('').reduce((acc, val) => {
const legend = 'aeiou';
let { vowels, consonants } = acc;
if(val.toLowerCase() === val.toUpperCase()){
return acc;
};
if(legend.includes(val.toLowerCase())){
vowels++;
}else{
consonants++;
};
return { vowels, consonants };
}, {
vowels: 0,
consonants: 0
});
};
console.log(countAlpha(str));输出结果
这将在控制台中产生以下输出-
{ vowels: 17, consonants: 29 }
