删除阵列中除1个以外的所有副本 - JavaScript

Question

我想删除重复的值并只保留一次该值。

实施例：

var myArray = ["blue","blue","red","red","green","blue","blue","red"]; 
//REMOVE DUPLICATES LEAVING ONE 
//results in - myArray = ["blue","red","green"]; 

Answer 1

可以筛选这样的（使用ES6语法）重复：

const myArray = ["blue","blue","red","red","green","blue","blue","red"]; 

const result = myArray.filter((a, i, arr) => arr.indexOf(a) === i); 

console.log(result);
