Getting started:

First you will need to download & install the AngularJS here's the link https://angularjs.org/.

And this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

script.js

var

app =

angular.module

(

"myModule"

,

[

]

)
.controller

(

"myController"

,

function

(

$scope)

{
var

members =

[
{

firstname:

"John"

,

lastname:

"Smith"

,

civil_status:

,

address:

"USA"

}
