In JavaScript:
const uniqueArray = [...new Set(arrayWithDuplicates)];This one-liner uses the Set object, which is a built-in JavaScript object that allows you to store unique values of any type, including primitive values and object references. By passing the arrayWithDuplicates array to the Set constructor, we create a new Set object containing only the unique elements of the array. We then use the spread syntax (...) to convert the Set object back to an array, which gives us an array with duplicates removed.
The result of this one-liner is assigned to the uniqueArray variable, which holds the new array with duplicates removed.
This one-liner is a concise and efficient way to remove duplicates from an array in JavaScript, using the built-in Set object and the spread syntax to convert the Set object back to an array. It avoids the need for a loop or conditional statements to find and remove duplicates, and can be easily adapted to handle other types of array operations that rely on built-in objects.
