JS의 배열 메서드 - reverse()

코드 예 1 -

const numberArray = [1,2,3,4,5];
const stringArray = ['A','B','C','D','E'];
const booleanArray = [true,true,false,true,false];
const objectArray = [
  {
  name:"Shubham",
  age:21
  },
  {
  name:"Shivam",
  age:25
  },
  {
  name:"Bharat",
  age:22
  },
]
const mixedArray = [1,2,3,"A","B","C",true,false,
{
   name:"Shivam",
  age:25
}
]



console.log(numberArray.reverse())
console.log(stringArray.reverse())
console.log(booleanArray.reverse())
console.log(objectArray.reverse())
console.log(mixedArray.reverse())

출력 -

[ 5, 4, 3, 2, 1 ]
[ 'E', 'D', 'C', 'B', 'A' ]
[ false, true, false, true, true ]
[
  { name: 'Bharat', age: 22 },
  { name: 'Shivam', age: 25 },
  { name: 'Shubham', age: 21 }
]
[ { name: 'Shivam', age: 25 }, false, true, 'C', 'B', 'A', 3, 2, 1 ]

코드 예제 2 - 문자열을 뒤집는 방법

const string = "hello"
const stringArray2 = []
for (let i of string){
  stringArray2.push(i)
}
stringArray2.reverse()
let reversedStr = stringArray2.join("").toString()
console.log(newStr)
