I would like to invoke an asynchronous function n times, invoking each time only after the previous one has resolved.

This is the code that works: 

async startGame() {
  for (let i = 0; i < this.totalNumberOfSets; i++) {
  await this.startSet();
  }
}

I would like to convert it to the Lodash function _.times.

I tried using this answer: Lodash: is it possible to use map with async functions?

this way:

async startGame() {
  await Promise.all(_.times(this.totalNumberOfSets, async () => {
    await this.startSet()
  }))
};

but all the function invoked immediately four times without waiting to resolve.

Also tried this:

  async startGame() {
   let resArray = [];
   await Promise.all(_.times(this.totalNumberOfSets, async () =>{
     let res = await this.startSet()
     resArray.push(res);
    }
  ))
 };

but it didn't work as expected as well.

Try using this package, which supports async/await in lodash https://www.npmjs.com/package/async-dash
