I had not remembered that I did actually already create one #BigInt #kata to learn the basics of it.

In #ES11 or #ES2020 or just #JavaScript 2 years ago it was released. Wanna learn it too? Feel free to fix some failing tests and hopefully learn actively how BigInt works.

BigInt: Basics A BigInt can represent numbers larger than number A BigInt is a large number a number: Number.MAX_VALUE * Number.MAX_VALUE, is useless, it results in Infinity a bigint: BigInt(Number.MAX_VALUE) * BigInt(Number.MAX_VALUE) results in an amazingly large AND usable number the result of BigInt(Number.MAX_VALUE) * BigInt(Number.MAX_VALUE) has 617 digits creating one can be done in multiple ways adding an n at the end of a number calling the function BigInt(x), where x is a number calling the function BigInt(x) with a string calling the function BigInt(x) with a binary number difference to a number a BigInt is of type "bigint" comparing via == can coerce a bigint to a number but type safe comparisons fail a bigint can NOT be used with Math.* functions can not be calculated with a number BigInt supports various operators the + and - work just like for numbers also * and / work the modulo operator % works as known the exponentiation operator ** works like on numbers but ++ even throws a SyntaxError the comparison operators work, even with numbers comparing 2n >= 2 works as if they were of the same type the number can also be the left operand 1 < 2n, works as if they were the same type explicit type conversion via String(0n) renders the number without a trailing n for Boolean(0b01n) everything but a 0 zero is true the API BigInt is NOT a constructor, it throws BigInt.asIntN() returns a bigint that can fit in the given number of bits BigInt.asUintN() uses the g...
