## Examples

Shows how to create and insert a field using a field builder.

```js
let doc = new aw.Document();

// A convenient way of adding text content to a document is with a document builder.
let builder = new aw.DocumentBuilder(doc);
builder.write(" Hello world! This text is one Run, which is an inline node.");

// Fields have their builder, which we can use to construct a field code piece by piece.
// In this case, we will construct a BARCODE field representing a US postal code,
// and then insert it in front of a Run.
let fieldBuilder = new aw.Fields.FieldBuilder(aw.Fields.FieldType.FieldBarcode);
fieldBuilder.addArgument("90210");
fieldBuilder.addSwitch("\\f", "A");
fieldBuilder.addSwitch("\\u");

fieldBuilder.buildAndInsert(doc.firstSection.body.firstParagraph.runs.at(0));

doc.updateFields();
doc.save(base.artifactsDir + "Field.CreateWithFieldBuilder.docx");
```
