With the indexOf method created, we can implement other methods such as the remove method:
remove(element) { const index = this.indexOf(element); return this.removeAt(index);}
We have already written a method that removes an element at a given position (removeAt). Now that we have the indexOf method, if we pass the element's value we can find its position and call the removeAt method, passing the position that we found. It is very simple, and it is also easier if we need to change the code from the removeAt method—it will be changed for both methods (this is what's nice about reusing code). This way, we do not need to maintain two methods to remove an item from the list—we need only one! Also, the ...
