BigInt and Symbol

BigInt - Large Integers

const big: bigint = 9007199254740993n // Note the 'n' suffix
const alsoBig: bigint = BigInt('9007199254740993')

// BigInt arithmetic
const sum = 1000000000000000000n + 1n // Works correctly!

Symbol - Unique Identifiers

const id: symbol = Symbol('userId')
const anotherId: symbol = Symbol('userId')

id === anotherId // false - each Symbol() creates a unique value!

1. Create largeNumber as the bigint 9007199254740993n
2. Create anotherLarge as the bigint 1000000000000000000n
3. Create sum by adding those two bigints
4. Create userId with Symbol('user-id')
5. Create anotherId with the same description Symbol('user-id')
6. Create areEqual by comparing userId === anotherId, then inspect the result
7. Export all six names
