輸出一個名稱和平均分數的表

Question

var member1 = prompt("Bowler's Name", "Name"); 
var member1score1 = prompt("Score from game 1", ""); 
var member1score2 = prompt("Score from game 2", ""); 
var member1score3 = prompt("Score from game 3", ""); 
var memeber1avg = ((memberscore1 + member1score2 + member1score3)/3); 


var member2 = prompt("Bowler's Name", "Name"); 
var member2score1 = prompt("Score from game 1", ""); 
var member2score2 = prompt("Score from game 2", ""); 
var member2score3 = prompt("Score from game 3", ""); 
var memeber2avg = ((memberscore1 + member1score2 + member1score3)/3); 


var member3 = prompt("Bowler's Name", "Name"); 
var member3score1 = prompt("Score from game 1", ""); 
var member3score2 = prompt("Score from game 2", ""); 
var member3score3 = prompt("Score from game 3", ""); 
var memeber3avg = ((memberscore1 + member1score2 + member1score3)/3); 


var member4 = prompt("Bowler's Name", "Name"); 
var member4score1 = prompt("Score from game 1", ""); 
var member4score2 = prompt("Score from game 2", ""); 
var member4score3 = prompt("Score from game 3", ""); 
var memeber4avg = ((memberscore1 + member1score2 + member1score3)/3); 

好吧，所以我是js的新手，我知道這可以做到更簡單的方法與數組...只是不知道如何。另外我該如何寫這個表格？

如何創建成員對象，並給它輸入和平均測算方法：由提示

function Member() { 
    this.score = []; 
    this.name = prompt("Bowler's Name", "Name"); 
} 

Member.prototype = { 

    inputScore: function(cnt){ 
    for (var i = 0; i < cnt; i++) { 
     this.score[i] = parseInt(prompt('Score from game ' + (i + 1), ''), 10); 
    } 
    }, 

    getAverage: function() { 
    var sum = 0; 
    for (var i = 0; i < this.score.length; i++) { 
     sum += this.score[i]; 
    } 
    return sum/this.score.length; 
    } 

}; 

// create four members and input data 
var members = []; 
for (var i = 0; i < 4; i++) { 
    members[i] = new Member(); 
    members[i].inputScore(3); 
} 

// output averages  
for (var i = 0; i < members.length; i++) { 
    alert('Average for ' + members[i].name + ' is ' + members[i].getAverage()); 
}
