Question

此功能正常。但是，如果我在str中添加更多的空格，那么它会给出错误的单词数。任何帮助，将不胜感激。

Answer 1

尝试类似：

mystring.split(/\s+/);

这将拆分一个或多个空格字符，因此一行中的两个空格（或更多）将被视为一个拆分。

Answer 2

let Allah = 'Allah    is our creator.'
Allah = Allah.trim();
count = 0;
for (let i = 0; i < Allah.length; i++) {
    let char = Allah[i];
    if (char == " " && Allah[i-1] != " ") {//add here
        count++;
    }
    
}
count++;
console.log(count);

//输出：4

当字符串中存在多个空格时，字数不正确
