Selecting array value for data clense

I am fairly new to react and lodash. I am trying to get some data rounded to two decimal places.

selectedPlayers {
0: {SHOT__Goals: 1.222222}
1: {SHOT__Goals: 0.888888}
}

 const goals = ( selectedPlayers ) => {
 const goal= _.round((selectedPlayers.SHOT__Goals), 2).toFixed(2);
 return goals;
 }

SHOT__Goals is coming in as undefined, how do I reference it so it knows to look inside of selectedPlayers

I want it to return values like 1.22 and 0.88

Actually, you don't need lodash for that, you could use the Array.prototype.map function:

const selectedPlayers = [{ SHOT__Goals: 1.222222 }, { SHOT__Goals: 0.888888 }];

const goals = selectedPlayers => selectedPlayers.map(player => player.SHOT__Goals.toFixed(2));

console.log(goals(selectedPlayers))

However, for what I gather you don't really want goals to be a function but the resulting array if I am right then the following would do:

const selectedPlayers = [{ SHOT__Goals: 1.222222 }, { SHOT__Goals: 0.888888 }];

const goals = selectedPlayers.map(player => player.SHOT__Goals.toFixed(2));

console.log(goals)

Something to notice:

  • I converted selectedPlayers to an array, it is easier to manipulate
  • I don't quite get why are you using _.round when there is also a toFixed

in this case... 

const selectedPlayers = {
  0: { SHOT__Goals: 1.222222 },
  1: { SHOT__Goals: 0.888888 }
}

const goals = selectedPlayers => {
  return _.round(selectedPlayers[0].SHOT__Goals, 2).toFixed(2)
}

console.log(goals(selectedPlayers))

Your example had a lot of issues, which i fixed. There are better ways of doing this however....
