## The Great Escape
|
||
|
|
|
||
|
|
### Escaping
|
||
|
|
|
||
|
|
**Quote delimiters** can be one of the tricky things to deal with.
|
||
|
|
|
||
|
|
Since they are used for delimiting text, they need a trick to include them in
|
||
|
|
our text.
|
||
|
|
|
||
|
|
For example, we want a `'` _(single quote)_ in or text, but use them as
|
||
|
|
delimiters:
|
||
|
|
|
||
|
|
```js
|
||
|
|
console.log('Houdini once said:')
|
||
|
|
console.log('Magic is the sole science not accepted by scientists,')
|
||
|
|
// Uh oh... ↙ JS thinks your string ends here
|
||
|
|
console.log(' because they can't understand it.')
|
||
|
|
// ...and new starts here ↖ that never finish !
|
||
|
|
// too bad ! a quote, ruined by quotes, ironic and very sad.
|
||
|
|
```
|
||
|
|
|
||
|
|
The `\` _(backslash)_ is used for that:
|
||
|
|
|
||
|
|
Everytime there is an _extra special_ character into your string, putting a `\`
|
||
|
|
in front of it will **escape** it and doing so will let JS understand you meant
|
||
|
|
the **litteral** following character and not the delimiter, _or whatever else
|
||
|
|
the character normaly means for a string_
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Nothing can stop you now with that new knowledge. Like Houdini, master of
|
||
|
|
escapes, you are going to escape some strings:
|
||
|
|
|
||
|
|
- Create a `escapeFromDelimiters` that includes all 3 quotes _(`` ` ``, `"` and
|
||
|
|
`'`)_.
|
||
|
|
|
||
|
|
- Create a `escapeTheEscape` that includes a backslash _(`\`)_.
