Using return data from an async function, in another function-CodePudding

I'm doing a little data analysis from chess.com data

I have this code

const getUsernames = async function() {
  let response = await chessAPI.getCountryPlayers('RE')
  names = [...response.body.players]
  //console.log(names)
  return names
}

const grabPlayerScores = async function() {
  let players = getUsernames()
  // let playerStats = [];
  for (i = 0; i = players.length; i  ) {
    let data = await chessAPI.getPlayerStats(i)
    console.log(data)
  }
}

grabPlayerScores();

I can't get the other function to await the return of the first. I know I should use promises or structure my other function differently but I'm still getting the hang of these types of functions.

CodePudding user response：

You need to add another await in your grabPlayerScores function to wait for getUsernames to finish.

const grabPlayerScores = async function() {
  // Add an 'await' here
  let players = await getUsernames();

  for(let i = 0; i = players.length; i  ) {
    let data = await chessAPI.getPlayerStats(i)
    console.log(data)
  }
}

I changed bit in your code,

const grabPlayerScores = async function () {
  let players = await getUsernames();
  for (i = 0; i = players.length; i  ) {
    let data = await chessAPI.getPlayerStats(players[i]);
    console.log(data)
  }
}
