<p><strong><code>WebAssembly.validate()</code> </strong>함수는 바이트가 유효한 wasm 모듈을 형성하는지 (<code>true</code>) 또는 생성하지 않는지 (<code>false</code>)를 반환하여 WebAssembly 바이너리 코드의 지정된 <a href="/ko/docs/Web/JavaScript/Typed_arrays">typed array</a>의 유효성을 검사합니다.</p>

<pre class="syntax">WebAssembly.validate(bufferSource);</pre>

<h3 id="Parameters">Parameters</h3>

<dl>
 <dt><code><em>bufferSource</em></code></dt>
 <dd>유효성을 검사 할 WebAssembly 바이너리 코드가 들어있는 <a href="/ko/docs/Web/JavaScript/Typed_arrays">typed array</a> 또는 <a href="/ko/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer">ArrayBuffer</a>입니다.</dd>
</dl>

<h3 id="Return_value">Return value</h3>

<p><code>bufferSource</code>가 유효한 wasm 코드 (<code>true</code>)인지 아닌지 (<code>false</code>)를 지정하는 부울입니다.</p>

<h3 id="Exceptions">Exceptions</h3>

<p><code>bufferSource</code>가 <a href="/ko/docs/Web/JavaScript/Typed_arrays">typed array</a>이나 <a href="/ko/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer">ArrayBuffer</a>가 아닌 경우 {{jsxref ( "TypeError")}}가 발생합니다.</p>

<p>다음 예제 (validate.html <a href="https://github.com/mdn/webassembly-examples/blob/master/js-api-examples/validate.html">source code</a> 참조 및 <a href="https://mdn.github.io/webassembly-examples/js-api-examples/validate.html">see it live</a>)는 .wasm 모듈을 가져 와서 형식화 된 배열로 변환합니다. 그런 다음 <code>validate()</code> 메서드를 사용하여 모듈이 유효한지 확인합니다.</p>

<pre class="brush: js">fetch('simple.wasm').then(response =&gt;
  response.arrayBuffer()
).then(function(bytes) {
  var valid = WebAssembly.validate(bytes);
  console.log("The given bytes are "
    + (valid ? "" : "not ") + "a valid wasm module");
});
