  1. Hello guys I have been learning and using Javascript for sometime now I have met a situation where I have 3 functions, where one has to wait for one another to finish executing the after they finished executing I have to go to some block of code. This 3 functions take some time to execute as they even have some database queries so they become left out so I heard thios can be fixed by promises but please help how can I use promises in this situation. Make simple code snippents please. E.g //create array of events event = []; //first function go to shop() if gone to shop is true add to array of events that I have gone to shop // second function buy the shoes() if bought shoes is true add to array of event that I have bought shoes //third function come back home() if came back to home is true add to array of events that came back //then check if array of events is empty if(eventsArray.lenght > 0) return that some function came true else return none succeded
