Best way to insert char in specific points of string in javascript?

Question

If I have the following string

"[Blah][Something.][Where.]"

What is the best way to locate wherever the "][" is and add a " + " in between them?

In other words, the resulting string should be:

"[Blah] + [Something.] + [Where.]"

Damascusi isn't asking about inserting characters as specific string indices, but rather, finding a pattern and replacing it with something else. — Julian H. Lam, Dec 14 '12 at 15:49

Using regular expressions...

var str = "[Blah][Something.][Where.]"
var newString = str.replace(/\]\[/g, ']+[');

I'd use split and join.

var string = "[Blah][Something.][Where.]".split("][").join("] + [");

If it was not a constant string, I would fallback to a regular expression and replace.
