How can I put [] (square brackets) in RegExp javascript?

Question

I\'m trying this:

str = \"bla [bla]\";
str = str.replace(/\\\\[\\\\]/g,\"\");
console.log(str);

And the replace doesn\'t work, what am I do

Answer 1

What exactly are you trying to match?

If you don't escape the brackets, they are considered character classes. This:

/[1\\]/

Matches either a 1 or a backslash. You may want to escape them with one backslash only:

/\[1\]/

But this won't match either, as you don't have a [1] in your string.
