# FunctionType

A TypeScript function declaration.

```ts
FunctionType: import("@alloy-js/core").Component<FunctionTypeProps> & {
    TypeParameters: import("@alloy-js/core").Component<import("./FunctionBase.jsx").TypeParametersProps> & Required<Pick<import("@alloy-js/core").Component<import("./FunctionBase.jsx").TypeParametersProps>, "tag">>;
    Parameters: import("@alloy-js/core").Component<import("./FunctionBase.jsx").FunctionTypeParametersProps> & Required<Pick<import("@alloy-js/core").Component<import("./FunctionBase.jsx").FunctionTypeParametersProps>, "tag">>;
}
```

## Remarks

Providing parameters and type parameters can be accomplished in one of three ways:

1. As an array of [TypeParameterDescriptor](../../types/typeparameterdescriptor/)s or [TypeParameterDescriptor](../../types/typeparameterdescriptor/)s. 2. As raw content via the `parametersChildren` or `typeParametersChildren` props. 3. As a child of this component via the \[unresolved link] or \[unresolved link] components.

## Example

```ts
(foo: string, bar: number) => void
```
