# --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.
|
|
|
|
```js
|
|
foo(0)
|
|
bar(0)
|
|
```
|
|
|
|
`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.
|
|
|
|
# --hints--
|
|
|
|
`orderMyLogic(4)` should return the string `Less than 5`
|
|
|
|
```js
|
|
assert(orderMyLogic(4) === 'Less than 5');
|
|
```
|
|
|
|
`orderMyLogic(6)` should return the string `Less than 10`
|
|
|
|
```js
|
|
assert(orderMyLogic(6) === 'Less than 10');
|
|
```
|
|
|
|
`orderMyLogic(11)` should return the string `Greater than or equal to 10`
|
|
|
|
```js
|
|
assert(orderMyLogic(11) === 'Greater than or equal to 10');
|
|
```
|
|

|
|
|
|
```js
|
|
function orderMyLogic(val) {
|
|
if (val < 10) {
|
|
return "Less than 10";
|
|
} else if (val < 5) {
|
|
return "Less than 5";
|
|
} else {
|
|
return "Greater than or equal to 10";
|
|
}
|
|
}
|
|
|
|
orderMyLogic(7);
|
|
```
|
|

|
|
```js
|
|
function orderMyLogic(val) {
|
|
if(val < 5) {
|
|
return "Less than 5";
|
|
} else if (val < 10) {
|
|
return "Less than 10";
|
|
} else {
|
|
return "Greater than or equal to 10";
|
|
}
|
|
}
|
|
```
