[JS] 陣列操作實務範例

Array操作系列文：http://chilin99999.tumblr.com/tagged/array%E6%93%8D%E4%BD%9C

這篇文章，舉幾個比較貼近實務的case，與大家分享。

如果大家想對Array做什麼害羞的事(?)，可以在底下留言。

版主會的話就將其補上～

let data = { title: 'Javascript超級大亂鬥', players: { teamA: [ { name: 'David', age: 18, score: 6688, }, { name: 'Peter', age: 16, score: 5689, } ], teamB: [ { name: 'Kelly', age: 62, score: 7566, }, { name: 'Diana', age: 24, score: 4089 } ] }, };

情境１：找出Diana是否為玩家

data.players.teamA.concat(data.players.teamB).some(d => d.name === 'Diana'); // true

情境２：從players清單中刪除Peter

Object.keys(data.players).forEach((key) => { let team = data.players[key]; let index = team.map(d => d.name).indexOf('Peter'); if(index > 0) team.splice(index, 1); });

情境３：找出分數最高的玩家

data.players.teamA.concat(data.players.teamB).reduce((pre, cur) => { return pre < cur ? pre : cur; }); // {name: "Diana", age: 24, score: 4089}

情境４：將新成員Tom隨機加入某隊

let playerTom = { name: 'Tom', age: 87, score: 8787, }; let randomTeam = Math.floor((Math.random()) + 1) ? 'teamA' : 'teamB'; data.players[randomTeam].push(playerTom);
