1.Create a array store the result. 2.Create a object to store info of no- repeat element. 3.Take out the element of array, and judge whether in the object. If not push into result array. Array.prototype.removeDuplicates =function(){varres =[];varjs ={};for(vari = 0; i <this.l...

There are multiple ways to remove duplicates from an array. The simplest approach (in my opinion) is to use theSetobject which lets you storeunique valuesof any type. In other words,Setwill automatically remove duplicates for us. constnames=['John','Paul','George','Ringo','John'];letuniq...
This post will go through how to remove duplicates ie. get distinct/unique values from an Array using ES6 Set. This gives you a one-line implementation of lodash/underscore’suniqfunction: constdedupe=list=>[...newSet(list)]; This rest of the post goes through the how and why this work...
2) Remove duplicates using filter and indexOf TheindexOf()method returns the first index at which a given element can be found in the array, or -1 if it is not present. Thefilter()method creates a shallow copy of a portion of a given array, filtered down to just the elements from ...

4、Array.prototype.filter() filter()方法创建一个新的数组,新数组中的元素是通过检查指定数组中符合条件的所有元素; 注意:filter()不会对空数组进行检测;不会改变原始数组; function remove(arr,item){ return arr.filter(function(ele){ return ele != item; ...

function.apply(newObj[, argsArray]) 方法可以修改指定函数的调用对象。function 是调用对象将被修改的函数,newObj 是函数的新调用对象,argsArray 是传递给function函数的参数,数组或者arguments对象。 apply 方法是将传递给函数的参数放入一个数组中,传入参数数组即可。
