## Gougle Search
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create the `queryServers` function, that takes 2 arguments:
|
||
|
|
- `serverName` a string of the name of the server
|
||
|
|
- `q` a string of the query given by the user
|
||
|
|
|
||
|
|
You have to construct 2 urls, using `q` as a search parameter,
|
||
|
|
prepending a `'/'` and for the 2nd appending `'_backup'`.
|
||
|
|
|
||
|
|
Then return the first value of those 2 calls
|
||
|
|
|
||
|
|
```js
|
||
|
|
queryServers('pouet', 'hello+world')
|
||
|
|
// return the fastest of those 2 calls:
|
||
|
|
// -> getJSON('/pouet?q=hello+world')
|
||
|
|
// -> getJSON('/pouet_backup?q=hello+world')
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
Create a `gougleSearch` function that takes a single query argument.
|
||
|
|
It must call `queryServers` in concurrently on 3 servers:
|
||
|
|
`'web'`, `'image'` and `'video'`.
|
||
|
|
|
||
|
|
A timeout of 80milliseconds must be set for the whole operation.
|
||
|
|
|
||
|
|
You must return the value from each servers in an object
|
||
|
|
using a the server name as key.
|
||
|
