javascript - 代码学院；程序无法在 JS 中运行

Question

所以代码学院说我正确地完成了这个任务，但它没有产生任何结果。它应该确定名称“Alex”在 var 文本中出现的次数。有人可以告诉我我做错了什么吗？

注意:当前代码的结果只是 = []

提前谢谢您，这是代码:

var text = "Alex, blah, Alex, blah, blah, blah, Alex, blah, Alex"

var myName = "Alex"
var hits = []

for (var i=0; i<text.length; i++){
    if (text[i] === "A"){
        for (var j = i; j < i + myName.length;j++){
            hits.push(j);
        }
    }
}

if (hits.length = 0){
    console.log("Your name wasn't found")
}
else{
    console.log(hits);
}

如果允许使用正则表达式，这非常简单......

var text = "Alex, blah, Alex, blah, blah, blah, Alex, blah, Alex"

var myName = "Alex"
var hits = []

hits = text.match(new RegExp( "\\b"+myName+"\\b", "g"));

if (hits.length == 0){
    console.log("Your name wasn't found")
}
else{
    console.log(hits);
}
