E0048: unexpected characters in hex literal
Hexadecimal (hex) number literals start with 0x and can only contain digits
0 through 9 and a through f (and optionally an n to signify a
BigInt). It is an error to include other letters in hex number literals:
let hungry = 0xfeedme;
To fix this error, fix or remove the extra digits or letters:
let hungry = 0xfeedad00d;
