I'm trying to find the positions of all occurrences of a string in another string, case-insensitive.

For example, given the string:

I learned to play the Ukulele in Lebanon.

and the search string le, I want to obtain the array:

[2, 25, 27, 33]

Both strings will be variables - i.e., I can't hard-code their values.

I figured that this was an easy task for regular expressions, but after struggling for a while to find one that would work, I've had no luck.

I found this example of how to accomplish this using .indexOf(), but surely there has to be a more concise way to do it?
