Guid.isValid() method

Indicates whether a GUID is valid, i.e. whether it would be successfully parsed by Guid.tryParse(). This function is cheaper than Guid.tryParse() because it does not construct a Guid object.

Signature:

static isValid(guid: string | undefined | null): boolean;

Parameters

Parameter	Type	Description
guid	string | undefined | null	The input string.

Returns:

boolean

true, if the Guid is valid.
