Keywords

Bnlang has a small, fixed set of keywords. Each English form has a Bangla synonym; both parse to the same token, so the language semantics are identical regardless of which form you use.

For the full alias catalog — keywords, globals, and module names — see Bilingual aliases.

What's not a keyword

If you're coming from JavaScript or Python, these are not in Bnlang:

let, const, do, async, await, yield, typeof, instanceof, in, void, delete, this, new, with, debugger, static.

Note: Bnlang uses wait (no async marker) for asynchronous values — see the Future page.
