- Create an Array: First, you create an array with some values. For example:
const myArray = [1, 2, 3, 4, 5];
In this step, myArray is an array that contains the numbers 1 through 5.
const mySet = new Set(myArray);
Here, mySet is a new set created from the elements in myArray. The Set constructor automatically removes duplicate values, so you will get a set containing only the unique elements.
- Result: After these steps, mySet is now a Set object that contains the unique elements from the original array. It automatically removes duplicates, so you have a collection of distinct values. Now, you can use the methods and properties of the Set object to work with your data. For example, you can check if a value exists in the set using the has method or iterate over the elements using a for…of loop.
Here is the complete code again for reference:
const myArray = [1, 2, 3, 4, 5]; const mySet = new Set(myArray);
Now, mySet contains the unique elements from myArray, and you can work with them using
the Set methods.
