# If Else
Tailwinds allows you to split your chatflow into different branches depending on If/Else condition.
### Input Variables
As noticed from the image above, it takes in any nodes that has `json` output. Some examples are: Custom Function, LLM Chain Output Prediction, Get/Set Variables.
You can then give a variable name:
This variable can then be used in the [If Function](#if-function) and [Else Function](#else-function) with the prefix `$`. For example:
```
$output
```
### If Else Name
You can name the node for easier visualization of what it does.
### If Function
This is a piece of JS code that is ran on Node sandbox. It must:
* Contains the `if` statement
* Returns a value within `if` statement
This gives much more flexibility for users to do complex comparison like regex, date comparsion and many more.
### Else Function
Similar to If Function, it must returns a value. This function will only be ran if the [If Function](#if-function) does not return a value.
### Output
When the [If Function](#if-function) successfully returns a value, it will be passed to the **True** output dot as shown above. This allow users to pass the value to the next node.
Otherwise, the returned value from [Else Function](#else-function) will be passed to the **False** output dot.
User can also take a look at the If Else template in the marketplace:
