It's important to note that:
* ASL is a distinct language with its own grammar, vocabulary, and syntax.
* Other sign languages exist in different parts of the world, and are not mutually intelligible with ASL.
* Deaf communities in the US and Canada primarily use ASL for communication.
* ASL is also used by hearing individuals who are involved in the Deaf community, such as interpreters and educators.
While ASL is the dominant sign language in the US and Canada, it is also used in other parts of the world due to the influence of American culture and education. However, it's important to remember that other sign languages are prevalent in different regions.
