如何使用JavaScript在给定的句子中找到大写单词并在该单词之前添加一个字符？
假设我们有一个包含一些大写英文字母的字符串，如下所示：
const str = "Connecting to server Connection has been successful We found result";
我们需要编写一个JavaScript函数，该函数接受一个这样的字符串，并在字符串中每个大写字母之前的空格之前插入一个逗号'。
为此的代码将是-
const str = "Connecting to server Connection has been successful We found
result";
const capitaliseNew = str => {
let newStr = '';
const regex = new RegExp(/.[A-Z]/g);
newStr = str.replace(regex, ',$&');
return newStr;
};
console.log(capitaliseNew(str));以下是控制台上的输出-
Connecting to server, Connection has been successful, We found result
