## Remove from a Set
|
|
 Remember to use <a>**`Read-Search-Ask`**</a> if you get stuck. Try to pair program  and write your own code 
|
|
|
|
###  Problem Explanation:
|
|
|
|
To solve this problem, you have to write a function for the class that removes a given element from the array if the array contains the given element.
|
|
|
|
|
|
##  Hint: 1
|
|
|
|
|
|
Use the built-in "has" function already created to test if the element exists in the Set.

|
|
|
|
##  Basic Code Solution:
|
|
|
|
this.remove = function(element){
|
|
if(this.has(element)) {
|
|
this.values().splice( this.values().indexOf(element), 1 );
|
|
}
|
|
}

|
### Code Explanation:
|
|
|
|
* The if statement checks if the collection contains the element.
|
|
* If the if statement evaluates to true, then starting from the index at which the element is located, one element is deleted.
|
|
* If the if statement evaluates to false, then nothing occurs.
