In this section, we will learn what the Set delete() method is and how to use it in JavaScript.
What is JavaScript Set delete() Method?
If we want to delete a specific element in a `Set` object, we use the `delete()` method.
JavaScript Set delete() Method Syntax:
delete(value)
delete() Function Parameters:
The method takes one argument and that is the value in which we want to be deleted from the target `Set` object.
delete() Function Return Value:
The return value of calling this method is `true` if the target value removed successfully, otherwise `false`.
The value `false` returns usually because the value we want it to be removed does not exist in the first place!
Example: using Set delete() method in JavaScript
const collect = new Set(); collect.add("Jack"); collect.add("Jack"); collect.add("Omid"); collect.add("John"); console.log(collect.delete("Jack")); console.log(collect.delete(1000));
Output:
true false
