trackBy function help angular to improve application performance by tracking or keeping a reference of the rendered data so that angular will not re-render the DOM tree for the same data assignment. we can use the trackBy function with *ngFor to track the objects in the loop. Angular can also track the objects if their order in the array is different, and this can be a good use case.
