Different methods to get unique array in JavaScript Method-1: Use the Set object Within the JavaScript environment, there is a native and built-in object called Set, which allows us to store unique values of any data type. The collections of values within a Set object may only occur once,...
Array.prototype.unique=function() {// 原数组先排序this.sort();// 构建一个新数组存放结果varnewArray = [];for(vari =1; i <this.length; i++) {// 检查原数组中的第i个元素与结果中的最后一个元素是否相同// 因为排序了,所以重复元素会在相邻位置if(this[i] !== newArray[newArray.length-1...
