How to delete brackets after a special letter in regex

Hi I am having problem while trying to remove these square brackets.

I figured out how to find square brackets but I need to find square brackets only if it starts with @ like this,

by the way I am using .replace to remove them in javascript, Not sure if it is going to help to find the answer.

@[john_doe]

The result must be @john_doe.

I dont want to remove other brackets which is like that,

[something written here]

Here is the link of the regex

You can use Regular expression /@\[/g:

const texts = ['@[john_doe]', '[something written here]']

texts.forEach(t => {
  // Match the @ character followed by an opening square bracket [
  const result = t.replace(/@\[/g, '@')
  console.log(result)
})

You need a regular expression replace solution like

text = text.replace(/@\[([^\][]*)]/g, "@$1")

See the regex demo.

Pattern details

  • @\[ - a @[ text
  • ([^\][]*) - Group 1 ($1): any zero or more chars other than [ and ] (the ] is special inside character classes (in ECMAScript regex standard, even at the start position) and need escaping)
  • ] - a ] char.

See the JavaScript demo:

let text = '@[john_doe] and [something written here]';
text = text.replace(/@\[([^\][]*)]/g, "@$1");
console.log(text);
