function WordCount(str) {
var totalSoFar = 0;
for (var i = 0; i < WordCount.length; i++)
if (str(i) === " ") { // if a space is found in str
totalSoFar = +1; // add 1 to total so far
}
totalsoFar += 1; // add 1 to totalsoFar to account for extra space since 1 space = 2 words
}
console.log(WordCount("Random String"));
我认为我已经很好地理解了这一点,除了我认为if陈述是错误的。怎么说if(str(i)包含空格,加1。
编辑:
我发现(感谢Blender)可以用更少的代码来做到这一点:
function WordCount(str) {
return str.split(" ").length;
}
console.log(WordCount("hello world"));
