对于字符串输出，将单引号替换为双引号

let str = 'Hello, World!';
let newStr = str.replace(/'/g, '"');
console.log(newStr);

str = "Hello, World!"
new_str = str.replace("'", "\"")
print(new_str)

String str = "Hello, World!";
String newStr = str.replace("'", "\"");
System.out.println(newStr);

$str = "Hello, World!";
$newStr = str_replace("'", "\"", $str);
echo $newStr;

string str = "Hello, World!";
string newStr = str.Replace("'", "\"");
Console.WriteLine(newStr);
