BigIntReserved
BigIntReserved is a term that might arise in discussions related to future JavaScript language features or potential reserved keywords. As of current JavaScript specifications, there is no official keyword or feature named "BigIntReserved". The term likely refers to a hypothetical or proposed addition to the language that would involve arbitrary-precision integers, which are now largely covered by the `BigInt` primitive type introduced in ECMAScript 2020. Before the introduction of `BigInt`, developers had to rely on external libraries to handle integers larger than the maximum safe integer value representable by the standard `Number` type. The concept of reserving a keyword like "BigIntReserved" might have been considered during the development of the `BigInt` feature to ensure clarity and prevent conflicts with future language evolution. However, the final specification opted for the more direct and descriptive `BigInt` keyword. Therefore, any mention of "BigIntReserved" is likely historical or speculative, relating to the design process of JavaScript's arbitrary-precision integer support.
