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...
If you like to have a function where you can send your lists, and get them back without duplicates, you can create a function and insert the code from the example above. Example defmy_function(x): returnlist(dict.fromkeys(x)) mylist =my_function(["a","b","a","c","c"]) ...
1) Remove duplicates using forEach and includes The Arrayincludes()method determines whether an array includes a certain value among its entries, returningtrueorfalseas appropriate. With this method, we will create a new empty array. All unique values from our array will be put into this array...
