Is there a decent way through which a pure pipe will trigger when adding or removing an item from the array employees? Cloning the array unto itself is not exactly clean, and marking it as not pure is way too demanding for only needing to check one type of change.
I don't get it, you said this.employees[0].name = "John" // this is a PURE change because we are changing a string Therefore why does it work in the first part of the video but not in the 2nd? Why is the pipe only executed once ?
Because in the first part the pipe was applied to a primitive (a string). If that string is changed, the pipe is triggered. In the second part, the pipe is applied to an object (an array). If you change a property on that object, it will not trigger the pure pipe, only if the whole object is changed (by reference).
great videos man, i would like to ask a big favor if you have a video on how to add order and order details in angular using firebase, many thanks in advance
