Combining Two JavaScript Arrays with Unique Elements

I am working with two arrays in JavaScript:

var list1 = ["Alice","Bob"];
var list2 = ["Bob", "Charlie"];

I want to achieve a result like this:

var list3 = ["Alice","Bob","Charlie"];

The resulting array should contain no duplicate entries.

Can someone guide me on how to merge these arrays in JavaScript while ensuring all elements are unique and retain their original order?

For more concepts, refer to Set in Wikipedia.

Hey there! Want to merge arrays while keeping unique values? JavaScript makes this easy! :rocket: You can use Sets to merge list1 and list2 while filtering out duplicates. Check it out:

let list1 = ["Alice", "Bob"];
let list2 = ["Bob", "Charlie"];
let list3 = [...new Set([...list1, ...list2])];

console.log(list3); // Output: ["Alice", "Bob", "Charlie"]

This method ensures your merged array is free of duplicates while maintaining the original order. Cool, huh? Let me know if this works for you!

Hey there! :rocket: If you’re looking to combine two arrays in JavaScript without duplicates and preserve the order, you’re in luck. JavaScript’s Set object is super handy for this! Here’s how you can do it:

var list1 = ["Alice", "Bob"];
var list2 = ["Bob", "Charlie"];
var list3 = Array.from(new Set(list1.concat(list2)));

console.log(list3); // Output: ["Alice", "Bob", "Charlie"]

By using Array.from along with Set, you can cleanly merge the arrays and ensure all elements remain unique. I’ve found this method works like a charm in my projects. Give it a try, and let me know if you have any questions! :blush:

Hey!

Use Set for unique merge:

const list1 = ["Alice", "Bob"];
const list2 = ["Bob", "Charlie"];
const list3 = [...new Set([...list1, ...list2])];

console.log(list3); // ["Alice", "Bob", "Charlie"]

Simple and effective!
