While writing "\" in Chrome console I get the following error:
VM242674:1 Uncaught SyntaxError: Invalid or unexpected token
In Firefox it gives following error:
Uncaught SyntaxError: '' string literal contains an unescaped line break
while writting "\\" gives:
"\\" in both browsers
What is the proper way to write "\" in JavaScript?
Do not let the rendering of a string in the console, which may display strings including escape sequences and wrapped in quotes because it is a debugging tool, confuse you.
If you want a slash in a string, then escape it with a second slash.
const string = "\\";
const node = document.createTextNode(string);
document.body.appendChild(node);
"\n" is a new line. So, "\" is the opening double quote of a string, followed by the escape sequence \" (which just means a " character in the string) but no closing double quote. This is interpretation tends to hold across many programming languages - Java, C#, PHP, just to name a few."\\" is the correct way to write \
Example: console.log('This will print as a single back slash \\')
'""'
