How to prevent string auto escaping?

Question

I have a variable var a = '\204444' , and I want to remove \ . I need the result to be 204444 .

I tried using a.replace(/\\/g, '') , but the result is not what I wanted.

Answer 1

If you have control over the variable initialisation you can do this

var a = String.raw`\204444`;
a.replace(/\\/g, '');

If you don't you can do this ( but that doesn't work if you have leading 0s )

var a = '\2304444';
a.charCodeAt(0).toString(8) + a.replace(/^./g, '');

Answer 2

Run this code snippet to check, it only work with string have escaped first char.

 var a='\204444'; a=a.replace(a[0], a.charCodeAt(0).toString(8)) console.log(a)
