## Remove from a Set
|
|
|
|
### Method:
|
|
- In this challenge we need to implement a `.remove()` method for the Set class we made in the previous challenge.
|
|
- The method should return `true` if the element was successfully removed and `false` otherwise.
|
|
### Solution:
|
|
```js
|
|
function Set() {
|
|
var collection = [];
|
|
this.has = function(element) {
|
|
return (collection.indexOf(element) !== -1);
|
|
};
|
|
this.values = function() {
|
|
return collection;
|
|
};
|
|
this.add = function(element) {
|
|
if(!this.has(element)){
|
|
collection.push(element);
|
|
return true;
|
|
}
|
|
return false;
|
|
};
|
|
this.remove = function(element){
|
|
if (this.has(element)){
|
|
collection.splice(collection.indexOf(element), 1);
|
|
return true;
|
|
}
|
|
return false;
|
|
}
|
|
}
|
|
```
