Regular expression: Strip the brackets from a portion of the text

I have a JavaScript application where I need to manipulate strings.

The text follows this structure:

  • It might begin with a prefix in square brackets [prefix]. I have to preserve this prefix with the brackets.
  • Next comes [whatever string], in this case I only need the text within the brackets.

For example:

[prefix][My title]

Returns: [prefix] My title

For example:

[Another title without prefix]

Returns: Another title without prefix

Answer №1

This code snippet will assist in recognizing text enclosed within brackets.

const keyRegex = /(?<=\[)(.*?)(?=\])/gmdi

To implement this, you can utilize Regex.exec() as demonstrated here. By following the example provided by Mozilla developers, you can compare if the first element of array1[0] matches the specified prefix. Happy coding!

Complex code may appear more "elegant" but can be challenging to comprehend, even for your future self (since comments cannot be used yet).
