***
### `Dynamic`
```go theme={null}
func Dynamic(attributes *map[string]interface{}) IResolvable
```
Creates a dynamic expression that can be used to loop over this iterator in a dynamic block.
As this returns an IResolvable you might need to wrap the output in
a Token, e.g. `Token.asString`.
See [https://cdktn.io/docs/concepts/iterators#using-iterators-for-list-attributes](https://cdktn.io/docs/concepts/iterators#using-iterators-for-list-attributes)
#### `attributes`Required
* *Type:* \*map\[string]interface\{}
***
### `ForExpressionForList`
```go theme={null}
func ForExpressionForList(expression interface{}) IResolvable
```
Creates a for expression that results in a list.
This method allows you to create every possible for expression, but requires more knowledge about
Terraform's for expression syntax.
For the most common use cases you can use keys(), values(), and pluckProperty() instead.
You may write any valid Terraform for each expression, e.g.
`TerraformIterator.fromList(myIteratorSourceVar).forExpressionForList("val.foo if val.bar == true")`
will result in `[ for key, val in var.myIteratorSource: val.foo if val.bar == true ]`.
As this returns an IResolvable you might need to wrap the output in
a Token, e.g. `Token.asString`.
#### `expression`Required
* *Type:* interface\{}
The expression to use in the for mapping.
***
### `ForExpressionForMap`
```go theme={null}
func ForExpressionForMap(keyExpression interface{}, valueExpression interface{}) IResolvable
```
Creates a for expression that results in a map.
This method allows you to create every possible for expression, but requires more knowledge about
Terraforms for expression syntax.
For the most common use cases you can use keys(), values(), and pluckProperty instead.
You may write any valid Terraform for each expression, e.g.
`TerraformIterator.fromMap(myIteratorSourceVar).forExpressionForMap("key", "val.foo if val.bar == true")`
will result in `\{ for key, val in var.myIteratorSource: key => val.foo if val.bar == true }`.
As this returns an IResolvable you might need to wrap the output in
a Token, e.g. `Token.asString`.
#### `keyExpression`Required
* *Type:* interface\{}
The expression to use as key in the for mapping.
***
#### `valueExpression`Required
* *Type:* interface\{}
The expression to use as value in the for mapping.
***

***
### `Keys`
```go theme={null}
func Keys() IResolvable
```
Creates a for expression that maps the iterators to its keys.
For lists these would be the indices, for maps the keys.
As this returns an IResolvable you might need to wrap the output in
a Token, e.g. `Token.asString`.
### `PluckProperty`
```go theme={null}
func PluckProperty(property *string) IResolvable
```
Creates a for expression that accesses the key on each element of the iterator.
As this returns an IResolvable you might need to wrap the output in
a Token, e.g. `Token.asString`.
#### `property`Required
* *Type:* \*string
The property of the iterators values to map to.
***
### `Values`
```go theme={null}
func Values() IResolvable
```
Creates a for expression that maps the iterators to its value in case it is a map.
For lists these would stay the same.
As this returns an IResolvable you might need to wrap the output in
a Token, e.g. `Token.asString`.

dvoIterator := terraformIterator_FromComplexList(cert.domainValidationOptions, jsii.String("domain_name"))
NewRoute53Record(this, jsii.String("record"), map[string]interface{}{
"allowOverwrite": jsii.Boolean(true),
