# JavaScript Transformation Service
|
|
|
|
Transform an input to an output using JavaScript.
|
|
|
|
It expects the transformation rule to be read from a file which is stored under the `transform` folder.
|
|
To organize the various transformations, one should use subfolders.
|
|
|
|
## Example
|
|
|
|
Let's assume we have received a string containing `foo bar baz` and we're looking for a length of the last word (`baz`).
|
|
|
|
transform/getValue.js:
|
|
|
|
```
|
|
(function(i) {
|
|
var array = i.split(" ");
|
|
return array[array.length - 1].length;
|
|
})(input)
|
|
```
