pull - 선택 값 골라내기

const pull = (arr, ...args) => {
  let argState = Array.isArray(args[0]) ? args[0] : args;
  let pulled = arr.filter((v, i) => !argState.includes(v));
  arr.length = 0;
  pulled.forEach(v => arr.push(v));
};

 

let myArray = ['a', 'b', 'c', 'a', 'b', 'c'];

pull(myArray, 'a', 'c');

// myArray = [ 'b', 'b' ]
