<h2 id="설명">설명</h2>

<p><code>Infinity</code>는 전역 객체의 속성입니다. 즉, 전역 스코프의 변수입니다.</p>

<p><code>Infinity</code>의 초기값은 {{jsxref("Number.POSITIVE_INFINITY")}}입니다. <code>Infinity</code>(양의 무한대)는 다른 어떤 수보다 더 큽니다.</p>

<p>수학적인 무한대와는 일부 차이점이 있습니다. {{jsxref("Number.POSITIVE_INFINITY")}} 문서에서 더 알아보세요.</p>

<p><code>Infinity</code>는 ECMAScript 5 명세에 따라 읽기 전용입니다.</p>
