Replace a character of a string

Question

I have a string that looks like this: [TITLE|prefix=a].

From that string, the text |prefix=a is dynamic. So it could be anything or emp

Answer 1

I think the solution to your problem would look similar to this:

let str = 'Lorem ipsum [TITLE|prefix=a] dolor [sit] amet [consectetur]';

str = str.replace(/(\[[^\|\]]+)(\|[^\]]*)?\]/g, "$1$2|suffix=z]");

console.log(str);
