## Keep Trying Or Giveup
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a `retry` function, that takes 2 arguments
|
||
|
|
- a `count`, that tells how many retries must be done
|
||
|
|
- an async `callback`, that will be call every try
|
||
|
|
|
||
|
|
and it return a new function, passing arguments given to the
|
||
|
|
callback on every tries.
|
||
|
|
|
||
|
|
> for count of 3, the function will be called at most 4 times:
|
||
|
|
> the initial call + 3 retries.
|
||
|
|
|
||
|
|
|
||
|
|
Create a `timeout` function, that takes 2 arguments
|
||
|
|
- a `delay`, that tells how long to wait
|
||
|
|
- an async `callback`, that will be call
|
||
|
|
|
||
|
|
and it return a new function, passing arguments given to the callback
|
||
|
|
and either the async callback resolve before the delay is reached,
|
||
|
|
in that case we return the value from the callback,
|
||
|
|
or reject an error using the message `"timeout"`
