# --description--
Order is important in `if`, `else if` statements.
The function is executed from top to bottom so you will want to be careful of what statement comes first.
Take these two functions as an example.
Here's the first:
```js
function foo(x) {
if (x < 1) {
return "Less than one";
} else if (x < 2) {
return "Less than two";
} else {
return "Greater than or equal to two";
}
}
```
And the second just switches the order of the statements:
```js
function bar(x) {
if (x < 2) {
return "Less than two";
} else if (x < 1) {
return "Less than one";
} else {
return "Greater than or equal to two";
}
}
```
While these two functions look nearly identical if we pass a number to both we get different outputs.

`foo(0)` will return the string `Less than one`, and `bar(0)` will return the string `Less than two`.
# --instructions--
Change the order of logic in the function so that it will return the correct statements in all cases.
