JavaScript中的new关键字是new运算符。它创建用户定义的对象类型的实例。
这是语法-
new constructor[([arguments])]
让我们看一个例子来学习new操作符的用法-
<!DOCTYPE html>
<html>
<body>
<p id="test"> </p>
<script>
var dept = newObject();
dept.employee = "David";
dept.department = "Programming";
dept.technology = "C++";
document.getElementById("test").innerHTML =
dept.employee + "is working on " + dept.technology + " technology.";
</script>
</body>
</html>
