# Function: scopeMatchesBase()

```ts
function scopeMatchesBase(preludeBase, baseNoDot): boolean;
```

Defined in: [packages/core/src/parse.ts:63](https://github.com/thedannywahl/cssdoc/blob/main/packages/core/src/parse.ts#L63)

Whether an `@scope`'s prelude base is the record's own base — exactly, or as the literal prefix of an
authored compound base selector built on it (e.g. a base of `pfx-transition.-transition-fade-entering`
for a prelude of `pfx-transition`). Only when this holds does `&`/`:scope` inside that `@scope` mean
"this record's own base" — otherwise the `@scope` belongs to a different record (commonly a parent
component reaching into this one as a member, or a sibling part's own scope), and `&`/`:scope` there
refer to THAT selector, not this record's.

## Parameters

### preludeBase

`string` | `undefined`

### baseNoDot

`string`

## Returns

`boolean`
