How To resolve multiple promise in typescript

Question

I have a service, which first loads a config file from server through an $http call then in it's success call back I am reading the file content, which actually contains a list of files to load from the server.

So I make another call to server to load all other files. Is there any way in TypeScript to return a promise which will get called only when all the promises are get resolved. Same like $q.all we had in angular 1.X

Answer 1

Promise.all([
    //task1,
    //task2,
    //task3,
  ]).then((value) => {doSomething()});

task can be any Promise call
