Flatten Javascript array

Question

I have an array of objects like this:

let list = [
  {
    \'items\': [
      \'item 1\',
      \'item 2\'
    ]
  },
  {
    \'items\': [
      \'item 3\'
    ]

You can flat the map() result using Array.prototype.flatMap():

The flatMap() method first maps each element using a mapping function, then flattens the result into a new array.

let list = [
  {
    'items': [
      'item 1',
      'item 2'
    ]
  },
  {
    'items': [
      'item 3'
    ]
  }
]
list = list.flatMap(i => i.items);

console.log(list);
