+# IsTuple\<T>
+
+## Overview
+
+주어진 타입이 튜플 타입인지 여부를 판별하는 타입이에요.
+
+## Syntax
+
+```ts
+type IsTuple<T> = T extends any[] | readonly any[]
+  ? number extends T['length']
+    ? false
+    : true
+  : false;
+```
+
+- **T**: 검사할 타입이에요.
+
+## Examples
+
+#### Example #1
+
+```ts
+type T0 = IsTuple<[]>; // true
+type T1 = IsTuple<[number]>; // true
+type T2 = IsTuple<[number, string]>; // true
+
+type T3 = IsTuple<any[]>; // false
+type T4 = IsTuple<unknown[]>; // false
+type T5 = IsTuple<number[]>; // false
+type T6 = IsTuple<Array<number>>; // false
+type T7 = IsTuple<ReadonlyArray<number>>; // false

+# IsTuple\<T>
+
+## Overview
+
+A type that determines whether the given type is a tuple type.
+
+## Syntax
+
+```ts
+type IsTuple<T> = T extends any[] | readonly any[]
+  ? number extends T['length']
+    ? false
+    : true
+  : false;
+```
+
+- **T**: The type to check.

+## Examples
+
+#### Example #1

+```ts
+type T0 = IsTuple<[]>; // true
+type T1 = IsTuple<[number]>; // true
+type T2 = IsTuple<[number, string]>; // true
