# Statements

## Overview

The `Statements` class provides essential control flow and error-handling structures for JavaScript. It enables managing loops with various conditions, , decision-making and handling errors.

The class also supports declaring variables with `js_flow_var()` and constants with `js_flow_const()`, offering flexibility in managing data within the code.

{
}
while ( # )
```

### for()

```js
var i = 0, j;
outer_loop: while (i < 10) {
	i++;
	j = 0;
	while (j < 10) {
		j++;
		if (j > i) continue outer_loop;
		application.output("i=" + i + ", j=" + j);
	}
}
```

**Sample**

```js
switch( # )
{
case:
default:
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.servoy.com/reference/servoycore/dev-api/js-lib/statements.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
