Funny enough JavaScript now has BigInt, which is purely integer:

It also has typed arrays (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Type...), but you can’t calculate with those values (you write floats into them that get rounded to integers, and values conceptually become floats when you read them)

WebAssembly has i32 and i64.
