blocks|key|634117|text|示例1和示例2的不同之处在于，在示例2中使用的是解构分配方法。这意味着，您可以对对象或数组进行析构，使对象的键作为变量。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|634118|因此，例如，如果我们使用这个简单的对象并开始破坏：|634119|​|634120|const+someObject+=+{

The difference between example one and example two is that you are using the <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment" rel="nofollow noreferrer">Destructuring Assignment</a> method in example two. That means, you can destruct an <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object" rel="nofollow noreferrer">Object</a>, or <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array" rel="nofollow noreferrer">Array</a> to have the keys of the object as variables.
So, for example if we take this simple object and we start destructuring:
<div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>const someObject = {
 something1: "1",
 something2: "2",
 something3: "3",
 something4: "4",

};

const { something1 } = someObject;
console.log(something1) // Returns 1</code></pre>
</div>
</div>

You see that we can use <code>something1</code> as a &quot;new variable&quot; instead of accessing it by using <code>someObject.something1</code>.
In your case you are including a module / class with the name <code>authController</code>, but if your module doesn't have a method or key called <code>authController</code>, using the following method:
<pre class="lang-js prettyprint-override"><code>const { AuthController } = ...
</code></pre>
won't work, because it's unable to access this method or key.
So, the first one: <code>authController.createUser()</code> will work because you are loading up the entire module without destructuring the module. If you do something like this <code>const { createUser } = require(&quot;authController&quot;)</code>, you can use it like <code>createUser(...)</code>

Difference between
<pre><code>const authController = require(&quot;../controller/authController&quot;); 
</code></pre>
and
<pre><code>const { authController } = require(&quot;../controller/authController&quot;);
</code></pre>
is, when your module exported by default from your .js file we use first syntax, while if there are several modules getting exported from a single .js file we use the second syntax. Also you cannot have more than one default export from a file. Hope that helps.

What is the difference between this
<pre><code>const authController = require(&quot;../controller/authController&quot;);
</code></pre>
and this
<pre><code>const { authController } = require(&quot;../controller/authController&quot;);
</code></pre>
my code doesnt work when i call a function like authController.createUser in second one and i wondered thats why?
Thanks for helps.
