|
Let's practice removing items from an ES6 Set using the `delete` method.
|
|
|
|
First, create an ES6 Set:
|
|
|
|
`var set = new Set([1,2,3]);`
|
|
|
|
Now remove an item from your Set with the `delete` method.
|
|
|
|
```js
|
|
set.delete(1);
|
|
console.log([...set]) // should return [ 2, 3 ]
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Now, create a set with the integers 1, 2, 3, 4, & 5.
|
|
|
|
Remove the values 2 and 5, and then return the set.
|
|
|
|
# --hints--
|
|
|
|
Your Set should contain the values 1, 3, & 4
|
|
|
|
```js
|
|
assert(
|
|
(function () {
|
|
var test = checkSet();
|
|
return test.has(1) && test.has(3) && test.has(4) && test.size === 3;
|
|
})()
|
|
);
|
|
```
|
|
|
|

|
|
|
|
```js
|
|
function checkSet(){
|
|
var set = null;
|
|
return set;
|
|
}
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
function checkSet(){
|
|
var set = new Set([1,2,3,4,5]);
|
|
set.delete(2);
|
|
set.delete(5);
|
|
return set;}
|
|
```
