Example:

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

Answer 1

You can filter duplicates like this (used ES6 syntax):

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

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

console.log(result);
