최솟값과 최댓값 reduce

reduce를 사용하는 방식은 아주 큰 값을 만났을 때 오류가 발생할 확률을 감소시키고, 앞선 방식보다 메모리 효율도 좋음

let a = [6, 5, 4, 3, 2];

함수 만들기

const reducerOne = (accumulator, currentvalue) => accumulator + currentvalue;
const reducerTwo = (accumulator, currentvalue) => accumulator - currentvalue;

최댓값

const reducerThree = (accumulator, currentvalue) 
=> accumulator > currentvalue ? accumulator : currentvalue;

console.log(a.reduce(reducerThree)); // 6

최솟값

const reducerThree = (accumulator, currentvalue) 
=> accumulator < currentvalue ? accumulator : currentvalue;

console.log(a.reduce(reducerThree)); // 1
