# Function: createWrapperFunction()

> **createWrapperFunction**(`analyzer`, `name`, `node`): `string` \| `undefined`

Defined in: [src/utils/javascript/helpers.ts:223](https://github.com/LuanRT/YouTube.js/blob/853a36307b5d644ada14dcb1216c2c22c2ae7b73/src/utils/javascript/helpers.ts#L223)

Analyzes an AST node to determine if it's a function call or a function
declaration. Based on that, it then creates a new JavaScript function as
a string. This new function acts as a wrapper, taking a single 'input' 
argument and forwarding it to the original function call.

Currently can handle:
- `CallExpression`: Creates a wrapper that invokes the function being called in the expression.
- `VariableDeclarator` with a `FunctionExpression`: Creates a wrapper that calls the declared function.

## Parameters

### analyzer

[`JsAnalyzer`](../../Types/classes/JsAnalyzer.md)

The `JSAnalyzer` instance, used to resolve context like declared variables.

### name

`string`

The name for the new wrapper function to be created.

### node

`Node`

The ESTree node.

## Returns

`string` \| `undefined`

## Todo

Look for edge cases.
