#Trick - Merge a JS array with 1 line of code (not as simple)

Hey Tricks Hunter !
Many thanks to your feedback about my last post ! your so awesome !

I have worked on a project, we do make an automatic legend on a map based on markers colors.

and the output of all markers colors repeat sometimes in array ex :

colors = ['rgb(0,255,0)','rgb(0,255,0)','rgb(0,255,0)','rgb(0,255,0)','rgb(0,0,255)','rgb(0,255,0)'] 

Let me know you, how to merge this array simply with a simple JS function.

let array = ['a','a','b','b','c','c']; let mergedArray = [...new Set(array)]; // output ['a','b','c']; 

The most important thing is ... is the new decomposition synthax in JS. If you use this, you set the variable content inside another.

exemple with object:

let datas = { age:27, gender:robot, } let users = { email:xxx@xxx.com, datas:...datas } // output : { email:xxx@xxx.com, datas:{ age:27, gender:robot, } } 

So if you combine
... and new Set() you do the trick with on line of code !
Cool no ?
