如何用JavaScript中的模式替换所有单词？

Question

给出以下字符串：

"Hello this is a :sample string :hello"

我想用其他内容替换:sample和:hello。我怎么能用JavaScript做到这一点？

这就是我的尝试：

var sentence = "Hello this is a :sample string :hello";
var words = sentence.split(" ");
for (var i = 0; i < words.length; i++) {
     if (words[i].startsWith(":")) {
       words[i] = words[i] + ":";
    }
}

sentence = words.join(" ");
console.log(sentence)

使用users。它可以接受特定的字符串或正则表达式。
