For loop using two variables?

I am working on some code where I have two variables with several different teams in them. I am new to JS and can't seem to understand how to print the value of both variables in the same for loop.

let jsonData = pm.response.json();
let home_team = []
let away_team = []
let home_team_id = []
let away_team_id = []
//console.log(jsonData)
jsonData.games.forEach((b)=>{
    home_team.push(b.home.name)
    away_team.push(b.away.name)

})

pm.environment.set("Home_Team",home_team)
pm.environment.set("Away_Team",away_team)
//console.log(pm.environment.get("Home Team"))
//console.log(pm.environment.get("Away Team"))

for (const element of home_team) {
  console.log(element + "VS" + away_team);
}

Now I know the code above will not run, I am just showing what I would like printed to console, I can't figure out how to add a second element that references away_team in the same looop. With that said when I set my for loop to

for (const element of home_team) {
  console.log(element);
}

It prints my list of home teams with no issues but I really am looking for a loop that prints both my home and away team, the list sizes are the same and always will be.

Thanks in advance.

If both of your arrays contain same number of items, then you can use an ordinary for loop with accessing each item with the same index as below -

let home_team = ["A", "B", "C"];
let away_team = ["D", "E", "F"];

for(let i=0; i<home_team.length; i++){
  console.log(`${home_team[i]} VS ${away_team[i]}`);
}

Alternatively, you can also use multiple counters in a for loop as below (though you won't need this now -

let home_team = ["A", "B", "C"];
let away_team = ["D", "E", "F"];

for(let i=0,j=2; i<home_team.length; i++, j--){
  console.log(`${home_team[i]} VS ${away_team[j]}`);
}

Just use an indexed for loop

for(let i = 0;i < home_team.length; i++) {
  console.log(home_team[i] + "VS" + away_team[i]);
}

You can also use forEach

home_team.forEach((item, index) => console.log(item + "VS" + away_team[index]));
