Replace a substring with special characters

I have a string that contains some substrings wrapped in some special characters. Here's my code:

var p = 'The quick brown fox jumps over the lazy [dog]. If the [dog] reacted, was it really lazy?';

var regex = /[\\[dog\\]]/g;

console.log(p.replace(regex, 'ferret'));

The code gives me output The quick brown fox jumps over the lazy ferretdogferret. If the ferretdogferret reacted, was it really lazy? but I am expecting The quick brown fox jumps over the lazy ferret. If the ferret reacted, was it really lazy?

replace javascript regex

Just remove the character set around the whole pattern, and just match \[dog\]:

var p = 'The quick brown fox jumps over the lazy [dog]. If the [dog] reacted, was it really lazy?';

var regex = /\[dog\]/g;

console.log(p.replace(regex, 'ferret'));

You could just use standard JS and approach it like below. 

let txt = 'The quick brown fox jumps over the lazy [dog]. If the [dog] reacted, was it really lazy?'

let txt1 = txt.split(' ')
txt1.map((word, i) => word.includes('dog') ? txt1[i]='ferret':null )
let sentence = txt1.join(' ')

console.log(sentence)
