SyntaxError Octal escape sequences are not allowed in strict mode.

I have a path to a file system, but when I use ts-node, it throws an error. How should I rewrite this so that I can get the file to work? Relevant Potion of code:

const DATAPATH = "C:\path\to\repo\advent-of-code\2022\01\data.txt";

const data = readFileSync(DATAPATH, "utf-8");

const DATAPATH = "C:\path\to\repo\advent-of-code\2022\01\data.txt";

const data = readFileSync(DATAPATH, "utf-8");

Error:

> ts-node ./lib/main.ts exec "-d" "2022-1"

C:\path\to\repo\advent-of-code\2022\01\runner.ts:10
const DATAPATH = `${"C:\path\to\repo\advent-of-code\2022\01\data.txt"}`;
                                                         ^

lmao probably need to escape it like \01 but you should prolly not make file paths like that

Jochem•2y ago

the quick and dirty fix is to switch to forward slashes, or use double back slashes

ErickO•2y ago

dirty indeed PepeLaugh

Jochem•2y ago

or honestly, just don't use a template literal, there's no reason to in this example

I tried without, same issue actually...

Jochem•2y ago

hm, then quick and dirty is forward slashes or double back slashes, more thorough is using something like this https://nodejs.org/api/path.html

Done, thanks!
