# TS2352: Conversion of type '…' to type '…' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.

> A type assertion (`as`) converts between two types that don't overlap at all, which is probably a mistake. Fix the value, or go through `unknown`.

## What it means

`x as T` is allowed when either type is assignable to the other. When the two types have
nothing in common, the assertion is almost certainly wrong, so it's reported.

## Example

```ts
const id = 42;

export const s = id as string;
```

## How to fix

- Convert the value instead: `String(id)`.
- If you really mean it, assert through `unknown`: `id as unknown as string`. That tells the
  checker to trust you; nothing checks it at runtime.
