Angular 8 and Observable that waits for another observable : <p>I need the data of observable1, but I need it only when observable2 is set to <code>true</code>. It is set to <code>true</code> AFTER the data of observable1 changes. How can I chain the two observables so that I will get the data of observable1 every time it changes, but that these results will wait for the change of observable2 before they are being used? </p>
