In this tutorial, we are going to learn about how to merge two arrays without duplicates in TypeScript. reactgo.com recommended courseTypescript: The Complete Developer's Guide Using Spread operator and new Set() To combine the two arrays without any duplicates, first we need to combine the...
Here’s another computer science classic: how do you merge two arrays? My preferred way in 2018 is to use the spread operator, though previously concat() was probably the most common approach. You can also use a for loop in interesting ways to achieve the same result. const a = [ 1,...
You can simply use the concat() method to merge two or more JavaScript arrays. This method does not change the existing arrays, but instead returns a new array.Let's try out the following example to understand how it basically works:
2 3 4 5 JavaScript Merge Two Arrays 6 7 8 9 let pets = ["Cat", "Dog", "Parrot"]; 10 let wilds = ["Tiger", "Wolf", "Zebra"]; 11 12 // Creating new array by combining pets and wilds arrays 13 var animals = pets.concat(wilds); 14 document.write(animals); //...
Example #2 In this example, we have taken three arrays and have merged them using the JavaScript concat() method. All the arrays have unique elements initially. constarr1=['A','B','C','D'];constarr2=['E','F','G'];constarr3=['H','I'];constresult=arr1.concat(arr2,arr3);...
