NgFor display n number of element

Question

I have time interval from 00 to 12 hours. I want to display a combo box option such as 00,01,02...12. How can I use ngFor in this case. There is no array or object declared. till index 12 I need to loop.

Answer 1

*ngFor="let hour of hours"

hours = ['00', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12'];
