I was trying to get a part of a string by splitting it but the character I'm using to split is a backslash and a hyphen. By researching around SO I found that you have to use double backslashes but that is not working too all I get is the string split in a weird way and a question mark in place of the backslash. How can I solve this? Any help is appreciated. Thanks in advance

x = 'uploads\20211116011817-natural'
console.log(x.split("'\'").pop().split('-')[0]) //expected the number between \ and -
