Angular 4.x: How to load random.js into ngOnInit ()?

Question

I'm new to angular 4.x I want to load change.js into the ngOnInit () function. How can I do this, I tried a little, but no one worked:

here is my code:

.....
    declare var chance: any;

    import 'src/assets/js/chance.js';
    ....
    ....
    export class ComposantComponent implements OnInit {
    ....
    ....
          ngOnInit() {
            this.http.get("src/app/datas/data.json")
              .subscribe((data)=> {
                setTimeout(()=> {
                  this.data = data.json();
                  this.data.forEach(function(row, index) {
                    row.checked = false;
                     // use chance here ... 
                  });

                  console.log(this.data[0]);
                  // console.log(chance);

                }, 500);
              });
          }
    ....
    ....
    ....
    }
