# Exercise 02 - repeatString
|
|
|
|
Write a function that simply repeats the string a given number of times:
|
|
|
|
```javascript
|
|
repeatString('hey', 3) // returns 'heyheyhey'
|
|
```
|
|
|
|
This function will take two arguments, `string` and `num`.
|
|
|
|
*Note:* The exercises after this one will not have arguments provided as this one does - you will need to provide them yourself from now on. So read each exercise's README carefully to see what kinds of arguments will be expected.
|
|
|
|
You will notice in this exercise that there are multiple tests (see in file `repeatString.spec.js`). Only the first test is currently enabled. So after making sure that this first one passes, enable the others one by one by deleting the `.skip` from the `test.skip()` function.
|
|
|
|
|
|
## Hints
|
|
|
|
- Take note of the above function call- how exactly is it being called?
|
|
|
|
- You're going to want to use a loop for this one.
|
|
|
|
- Create a variable to hold the string you're going to return, create a loop that repeats the given number of times and add the given string to the result on each loop.
|
|
|
|
- If running `npm test repeatString.spec.js` returns results similar to the below, make sure you have enabled the rest of the tests, as described in the instructions above.
