# --description--
|

|

|

|
|
Sometimes, you need to match a character (or group of characters) that appears one or more times in a row. This means it occurs at least once, and may be repeated.
|
||
|
|
|
||
|
|
You can use the `+` character to check if that is the case. Remember, the character or pattern has to be present consecutively. That is, the character has to repeat one after the other.
|
||
|
|
|
||
|
|
For example, `/a+/g` would find one match in `"abc"` and return `["a"]`. Because of the `+`, it would also find a single match in `"aabc"` and return `["aa"]`.
|
||
|
|
|
||
|
|
If it were instead checking the string `"abab"`, it would find two matches and return `["a", "a"]` because the `a` characters are not in a row - there is a `b` between them. Finally, since there is no `"a"` in the string `"bcd"`, it wouldn't find a match.
|
||
|
|
|

|
# --instructions--
|
||
|
|
|
||
|
|
You want to find matches when the letter `s` occurs one or more times in `"Mississippi"`. Write a regex that uses the `+` sign.
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
Your regex `myRegex` should use the `+` sign to match one or more `s` characters.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(/\+/.test(myRegex.source));
|
||
|
|
```
|
||
|
|
|
||
|
|
Your regex `myRegex` should match 2 items.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(result.length == 2);
|
||
|
|
```
|
||
|
|
|
||
|
|
The `result` variable should be an array with two matches of `"ss"`
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(result[0] == 'ss' && result[1] == 'ss');
|
||
|
|
```
|
||
|
|
|
