Subject: How to extract only needed attribute from an array


I have an object called Tags with id and name ==> [ tag.id , tag.name]

| [1 , aaa]   |

| [ 3 , bbb]  |

| [ 5 , ccc]  |

| [ 6 , dfd]  |

| [ 7 , waf]  |

| [ 11 , vee] |

There is an array with the list of tags , i just want to extract all
tag.id
as a new array, what is the easiest way to do
