🌱 Split array by an value

Trong ruby, khi muốn split một array ra 2 arrays theo value, có thể sử dụng method slice_after(method slice_before cũng tương tự, chỉ khác vị trí split)

array = [
  {activity: "1", ticket: "123"},
  {activity: "2", ticket: "123"},
  {activity: "3", ticket: ""},
  {activity: "4", ticket: "234"},
]
 
array.slice_after { |i| i.activity == "3" }
# Returns:
[
  [
    {activity: "1", ticket: "123"},
    {activity: "2", ticket: "123"},
    {activity: "3", ticket: ""}
  ],
  [
    {activity: "4", ticket: "234"}
  ]
]
 
array.slice_before { |i| i.activity == "3" }
# Returns:
[
  [
    {activity: "1", ticket: "123"},
    {activity: "2", ticket: "123"}
  ],
  [
    {activity: "3", ticket: ""},
    {activity: "4", ticket: "234"}
  ]
]
