Given a 2D array, write a function that flips it vertically or horizontally.

flipArray.js

  let array = [
    [1,2,3],
    [4,5,6],
    [7,8,9]
    ]
    
  const flip = (arr, type) => {
    let newList = [];
    if (type === 'horizontal') {
      for(const item of arr) {
        newList.push(item.slice().reverse());
      }
    }

    if (type === 'vertical') {
      newList = [...arr].reverse();
    }

    console.log(newList);
    return newList;
  };



  flip(array, 'vertical')
  flip(array, 'horizontal')
