Answer 1

const getCheckedItems = list => list.filter(item => item.checked)

var res = getCheckedItems([
  {checked: false, name: '张三'},
  {checked: false, name: '李四'},
  {checked: true, name: '王五'},
  {checked: false, name: '赵六'},
  {checked: true, name: '李七'},
])

console.log(JSON.stringify(res)) // => [{"checked":true,"name":"王五"},{"checked":true,"name":"李七"}]
