# Which values does the while loop show?
|
|
|
|
For every loop iteration, write down which value it outputs and then compare it with the solution.
|
|
|
|
Both loops `alert` the same values, or not?
|
|
|
|
1. The prefix form `++i`:
|
|
|
|
```js
|
|
let i = 0;
|
|
while (++i < 5) alert( i );
|
|
```
|
|
2. The postfix form `i++`
|
|
|
|
```js
|
|
let i = 0;
|
|
while (i++ < 5) alert( i );
|
|
```
