数组中元素(字符串）的总和

我正在制作一个程序，根据我在sm4sh中使用的6个字符，向我输出帮助对方进行大量好匹配的字符，帮助对方进行坏匹配，例如，我使用罗莎琳娜，她对马里奥不利，但对加农多夫来说，匹配对我有点有利，我现在想做的是数组中所有元素的总和，以检查我的6个字符的所有数组中的54个字符（暂时不要有不平衡的数组）。谢谢

带ROSALINA

var rosalina_good_matches = ["Ganondorf","King Dedede","Little Mac","Jigglypuff","Duck Hunt","Bowser","Zelda","Dr Mario","Charizard","Donkey Kong","Mr Game and Watch","Robin","Wario","Ness","Palutena","Wii Fit Trainer","Peach","Mewtwo","Samus","Mega Man","ROB","Lucina","Pac-Man","Falco","Toon Link","Yoshi","Marth","Ike","Link","Villager","Kirby","Greninja","Roy","Diddy Kong","Shulk","Luigi","Fox","Lucario","Meta Knight","Olimar","Sonic","Corrin","Sheik"];
var rosalina_even_matches = ["Pit","Dark Pit","Lucas","Captain Falcon","Pikachu","Bayonetta","Cloud"];
var rosalina_bad_matches = ["Mario","Zero Suit Samus","Ryu"];
//Check the sum of 54 characters
for(var i = 0;i < rosalina_good_matches.length;i++){
    console.log(rosalina_good_matches[i]);
}
