Enum Constant 

pub enum Constant {
    Number(NumberBits),
    Int32(i32),
    String(EcmaString),
    Boolean(bool),
    Null,
    Undefined,
    BigInt(BigIntLiteral),
}

Persistable values. Heap references, holes, and uninitialized sentinels are intentionally absent because they are runtime identities/states. String constants back property keys, global names, private-name descriptions, regular-expression pattern/flags, module specifiers, and export names.

Variants

Number(NumberBits)

Int32(i32)

String(EcmaString)

Boolean(bool)

Null

Undefined

BigInt(BigIntLiteral)
