# --description--
|
|
|
|
You learned about searching for whitespace using `\s`, with a lowercase `s`. You can also search for everything except whitespace.
|
|
|
|
Search for non-whitespace using `\S`, which is an uppercase `s`. This pattern will not match whitespace, carriage return, tab, form feed, and new line characters. You can think of it being similar to the character class `[^ \r\t\f\n\v]`.
|
|
|
|
```js
|
|
let whiteSpace = "Whitespace. Whitespace everywhere!"
|
|
let nonSpaceRegex = /\S/g;
|
|
whiteSpace.match(nonSpaceRegex).length; // Returns 32
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Change the regex `countNonWhiteSpace` to look for multiple non-whitespace characters in a string.
|
|
|
|
# --hints--
|
|
|
|
Your regex should use the global flag.
|
|
|
|
```js
|
|
assert(countNonWhiteSpace.global);
|
|
```
|
|
|
|
Your regex should use the shorthand character `\S` to match all non-whitespace characters.
|
|
|
|
```js
|
|
assert(/\\S/.test(countNonWhiteSpace.source));
|
|
```
|
|
|
|
Your regex should find 35 non-spaces in `"Men are from Mars and women are from Venus."`
|
|
|
|
```js
|
|
assert(
|
|
'Men are from Mars and women are from Venus.'.match(countNonWhiteSpace)
|
|
.length == 35
|
|
);
|
|
```
|
|
|
|
Your regex should find 23 non-spaces in `"Space: the final frontier."`
|
|
|
|
```js
|
|
assert('Space: the final frontier.'.match(countNonWhiteSpace).length == 23);
|
|
```
|
|
|
|
Your regex should find 21 non-spaces in `"MindYourPersonalSpace"`
|
|
|
|
```js
|
|
assert('MindYourPersonalSpace'.match(countNonWhiteSpace).length == 21);
|
|
```

```js
