console.log 将显示传递给 log 方法的参数控制台窗口.使用此方法在控制台窗口.

console.log will display the parameter passed to the log method in the console window. Use this method to display a string or variable in the console window.

您也可以在代码中使用控制台类，就像我们一样使用 JavaScript 警报.

You can use the console class in your code as well, much like we can use JavaScript alerts.

<script type = "text/javascript"> 
    function tryConsole() { 
        console.log("hello world"); 
    } 
</script>

当使用return语句时，函数将停止执行，并返回指定的值.

When using the return statement, the function will stop executing, and return the specified value.
