为什么节点不能在我的终端或浏览器中运行javascript函数？

Question

I'm using node.js to run JavaScript in my terminal. When I run the following JavaScript file (testfile.js) in my terminal with the command "node testfile.js", here's what I get:

console.log("meh");

=> meh

So that works fine. But when I make it a function like this:

function sayMeh() {
    console.log("meh");
};

sayMeh;

=> 

I get no result. Why? How can I test JS to see if it works?

Answer 1

您需要调用函数，而不仅仅是提及它。

sayMeh();
