Do I need to escape these in javascript?

Question

My strings will hold the values:

"["
"[/blah]"

do I need to escape anything?

Is it just doubling the /?

Answer 1

Escape for what purpose? I at least don't see any XSS risks in the particular string.

Answer 2

you don't have to do anything / is not a special character

Answer 3

If your string are "[" "[/blah]", then you don't need to escape anything if you use single quote:

var foo = '"[" "[/blah]"';

Answer 4

Since this is a literal string square brackets or forward slash will not be interpreted so in your example you don't need to escape anything. Doubling applies to a backward slash only \
