숫자와 문자열을 포함한 배열의 정렬

숫자와 문자열을 포함한 배열의 정렬할 경우

localeCompare()이라는 함수를 사용한다

// 오름차순
const getSingleValueAsc = (arr) => {
  return arr.sort(function (a, b) {
    return a.localeCompare(b, undefined, {
      numeric: true,
      sensitivity: 'base',
    });
  });
};
// 내림차순
const getSingleValueDesc = (arr) => {
  return arr.sort(function (a, b) {
    return b.localeCompare(a, undefined, {
      numeric: true,
      sensitivity: 'base',
    });
  });
};
console.log(getSingleValueAsc(strNum));
// [ 'a1', 'a2', 'a10', 'a12', 'j1', 'j2', 'j5', 'j10', 'j13', 'j19' ]
console.log(getSingleValueDesc(strNum));
// [ 'j19', 'j13', 'j10', 'j5', 'j2', 'j1', 'a12', 'a10', 'a2', 'a1' ]

숫자와 문자열을 포함한 객체를 포함한 배열의 정렬할 경우

const valueOfKeyArr = [
  { name: 'a10', foo: 'foo', bar: 'bar' },
  { name: 'a2', foo: 'foo', bar: 'bar' },
  { name: 'a1', foo: 'foo', bar: 'bar' },
  { name: 'a12', foo: 'foo', bar: 'bar' },
  { name: 'joker5', foo: 'foo', bar: 'bar' },
  { name: 'joker10', foo: 'foo', bar: 'bar' },
  { name: 'joker2', foo: 'foo', bar: 'bar' },
  { name: 'joker1', foo: 'foo', bar: 'bar' },
  { name: 'joker13', foo: 'foo', bar: 'bar' },
  { name: 'joker9', foo: 'foo', bar: 'bar' },
];

// 오름차순
const getValueOfKeyAsc = (arr, key) => {
  return arr.sort(function (a, b) {
    const valueOfKeyA = a[key].toUpperCase();
    const valueOfKeyB = b[key].toUpperCase();
    return valueOfKeyA.localeCompare(valueOfKeyB, undefined, {
      numeric: true,
      sensitivity: 'base',
    });
  });
};
//내림차순
const getValueOfKeyDesc = (arr, key) => {
  return arr.sort(function (a, b) {
    const valueOfKeyA = a[key].toUpperCase();
    const valueOfKeyB = b[key].toUpperCase();
    return valueOfKeyB.localeCompare(valueOfKeyA, undefined, {
      numeric: true,
      sensitivity: 'base',
    });
  });
};

getValueOfKeyAsc(valueOfKeyArr, 'name');
/*
[
  { name: 'a1', foo: 'foo', bar: 'bar' },
  { name: 'a2', foo: 'foo', bar: 'bar' },
  { name: 'a10', foo: 'foo', bar: 'bar' },
  { name: 'a12', foo: 'foo', bar: 'bar' },
  { name: 'joker1', foo: 'foo', bar: 'bar' },
  { name: 'joker2', foo: 'foo', bar: 'bar' },
  { name: 'joker5', foo: 'foo', bar: 'bar' },
  { name: 'joker9', foo: 'foo', bar: 'bar' },
  { name: 'joker10', foo: 'foo', bar: 'bar' },
  { name: 'joker13', foo: 'foo', bar: 'bar' }
]
*/

getValueOfKeyDesc(valueOfKeyArr, 'name');
/*
[
  { name: 'joker13', foo: 'foo', bar: 'bar' },
  { name: 'joker10', foo: 'foo', bar: 'bar' },
  { name: 'joker9', foo: 'foo', bar: 'bar' },
  { name: 'joker5', foo: 'foo', bar: 'bar' },
  { name: 'joker2', foo: 'foo', bar: 'bar' },
  { name: 'joker1', foo: 'foo', bar: 'bar' },
  { name: 'a12', foo: 'foo', bar: 'bar' },
  { name: 'a10', foo: 'foo', bar: 'bar' },
  { name: 'a2', foo: 'foo', bar: 'bar' },
  { name: 'a1', foo: 'foo', bar: 'bar' }
]
