+## 题目描述
+
+<!-- 这里写题目描述 -->
+
+<p>Given a function <code>fn</code>, an array of&nbsp;arguments&nbsp;<code>args</code>, and a timeout&nbsp;<code>t</code>&nbsp;in milliseconds, return a cancel function <code>cancelFn</code>.</p>
+
+<p>After a delay of&nbsp;<code>t</code>,&nbsp;<code>fn</code>&nbsp;should be called with <code>args</code> passed as parameters <strong>unless</strong> <code>cancelFn</code> was invoked before the delay of <code>t</code> milliseconds elapses, specifically at <code>cancelT</code>&nbsp;ms.&nbsp;In that case,&nbsp;<code>fn</code> should never be called.</p>
+
+<p>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre>
+<strong>Input:</strong> fn = (x) =&gt; x * 5, args = [2], t = 20, cancelT = 50
+<strong>Output:</strong> [{&quot;time&quot;: 20, &quot;returned&quot;: 10}]
+<strong>Explanation:</strong> 
+const cancel = cancellable((x) =&gt; x * 5, [2], 20); // fn(2) called at t=20ms
+setTimeout(cancel, 50);
+
+The cancellation was scheduled to occur after a delay of cancelT (50ms), which happened after the execution of fn(2) at 20ms.
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre>
+<strong>Input:</strong> fn = (x) =&gt; x**2, args = [2], t = 100, cancelT = 50 
+<strong>Output:</strong> []
+<strong>Explanation:</strong> 
+const cancel = cancellable((x) =&gt; x**2, [2], 100); // fn(2) not called
+setTimeout(cancel, 50);
+
+The cancellation was scheduled to occur after a delay of cancelT (50ms), which happened before the execution of fn(2) at 100ms, resulting in fn(2) never being called.
+</pre>
+
+<p><strong class="example">Example 3:</strong></p>
+
+<pre>
+<strong>Input:</strong> fn = (x1, x2) =&gt; x1 * x2, args = [2,4], t = 30, cancelT = 100
+<strong>Output:</strong> [{&quot;time&quot;: 30, &quot;returned&quot;: 8}]
+<strong>Explanation:</strong>
+const cancel = cancellable((x1, x2) =&gt; x1 * x2, [2,4], 30); // fn(2,4) called at t=30ms
+setTimeout(cancel, 100);
+
+The cancellation was scheduled to occur after a delay of cancelT (100ms), which happened after the execution of fn(2,4) at 30ms.
