설명
Infinity는 전역 객체의 속성입니다. 즉, 전역 스코프의 변수입니다.
Infinity의 초기값은 Number.POSITIVE_INFINITY입니다. Infinity(양의 무한대)는 다른 어떤 수보다 더 큽니다.
수학적인 무한대와는 일부 차이점이 있습니다. Number.POSITIVE_INFINITY 문서에서 더 알아보세요.
Infinity는 ECMAScript 5 명세에 따라 읽기 전용입니다.
예제
console.log(Infinity); /* Infinity */ console.log(Infinity + 1); /* Infinity */ console.log(Math.pow(10,1000)); /* Infinity */ console.log(Math.log(0)); /* -Infinity */ console.log(1 / Infinity); /* 0 */ console.log(1 / 0); /* Infinity */
