JavaScript/REGEX: Replace the 3rd match
Using JavaScript and Regular Expressions, how can I replace the third match?
For example, I want JavaScript to return this:
hello[11][22][X][44][55]'
For example, I want JavaScript to return this:
hello[11][22][X][44][55]'

Is there a way to accommodate the possibility of text between brackets in the strong?
In the example below, [33] should be replaced with [X] in both scenarios.
In the example below, [33] should be replaced with [X] in both scenarios.
var str = 'hello[11][22][33][44][55]';
var str = 'hello[11][world][22][example7][33][value][44][test][55]';
Now [33] is not the third bracketed set of characters. It is the fifth. How do you know to replace the fifth one in this case? Or are you always replacing [33] precisely?
