Before we do so. Any improvements to the API?
Could be replaced, more or less, with this:
const PATTERN = /\\(?:([rnvft"'`\\bae])|x([a-fA-F0-9]{2})|u([a-fA-F0-9]{4}))/g;
const CHARS = {
r: '\r',
n: '\n',
v: '\v',
f: '\f',
t: '\t',
'"': '"',
"'": "'",
'`': '`',
'\\': '\\',
b: '\b',
a: 'a',
e: '\x1b'
};
export default str =>
str.replace(PATTERN, (_, char, hex, unicode) =>
char ? CHARS[char] : String.fromCharCode(parseInt(hex ?? unicode, 16))
);If someone wants to update this a bit and modernize the implementation (as above), feel free to open a PR and I can take a look.
