I've gotten a Random Lotto Generator script to work in JavaScript in one game. Now, I'm trying to get it to function for multiple Lotto games and figured Objects were the best way to adjust to the different formats of each game to account for different number pools, different selected numbers, 'bonus balls', duplicate numbers, etc.

const game = [{name: "Lotto Texas", balls: 6, numbers: 54, start: 1, duplicates: false, bonusBall: false, results: []},
{name: "Pick 3", balls: 3, numbers: 10, start: 0, duplicates: true, bonusBall: false, results: []},
{name: "Powerball", balls: 5, numbers: 69, start: 1, duplicates: false, bonusBall: true, bonusNumbers: 26, results: [], bonus: []}];

game.forEach (lottoResults()); // gets results

function lottoResults(){
    this.results.length = this.balls; //Here is where the error occurs. This is supposed to assign the balls property to the results array's length value.
 
    if (!this.duplicates){ //checks if duplicates allowed
        this.results.forEach(duplicateCheck());
    }
    else{
       this.results.forEach(lottoBall())
    }
    
    if(this.bonusBall){
        this.bonus.push(lottoBall(this.bonusNumbers, this.start)); //assigns a number to bonus ball
    }
}

I'm trying to set a blank array initialized in each object, with the amount with the 'balls' property (referring to lotto balls) setting how big the array is dependent on the game. However, anytime I try to set that up, I keep getting an Uncaught TypeError: Undefined is not a function. I've tried setting the object property value to a primitive variable, establishing the array length within the initialized object variables, but still get the same error in some form. Am I just misusing the object and should be calling the values differently?
