E0016: expected hexadecimal digits in Unicode escape sequence
In variable names and strings, a Unicode escape sequence must contain only
hexadecimal digits (any of 0123456789abcdefABCDEF). It is an error if other
characters appear within a Unicode escape sequence:
console.log("List of Pok\ue9mon by weight:");
console.log("{Nidoran\u{2642male}");
For an escape sequence without { and }, add { and }:
console.log("List of Pok\u{e9}mon by weight:");
Alternatively, for an escape sequence without { and }, include 0 digits
such that the escape sequence contains exactly four hexadecimal digits:
console.log("List of Pok\u00e9mon by weight:");
For an escape sequence with { and }, ensure the } appears after the
hexadecimal digits:
console.log("{Nidoran\u{2642}male}");
