utils.idGenerator.getNextUniqueId() function

Generate the next unique element IDs. IDs are compatible with the HTML4 'id' attribute restrictions: Use only ASCII letters, digits, '_', '-' and '.'

For UUIDs use genUid (below) instead; this ID generator should primarily be used for IDs that end up in the DOM.

Signature:

export declare function getNextUniqueId(): string;

Returns:

string

The next unique identifier.
