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

Two backslashes produces a single backslash, so you're searching for "a backslash, followed by a character class consisting of a 1 or a right bracket, and then you're missing an closing bracket.

Try

str.replace(/\[1\]/g, '');
