isValidPresentationId
function isValidPresentationId(value: unknown): value is string;
At least 25 characters of letters, digits, hyphens and underscores — the id from a Slides URL. The format is all that is checked.
isX and nonX answer a question and never interrupt control flow; requireX and requireNonX hand the value back or throw. The scheme is explained in Validation conventions.
Parameters
Parameter | Type | Description |
|---|---|---|
|
| The value to check. |
Returns
boolean — true when the value is a presentation id; otherwise false.
In TypeScript the guard narrows value to string inside the branch.
