JAVASCRIPT: Count the number of REGEX results

Question

This is what regex should find { anything in it }, and then I want to count the number of results what the regex found.

So I have a string like this:

{example1}{example2}{example3} in this case the count number is 3

11

you need the global regex flag (g) to match all occurrences and then simply get the length of the result. the ? makes the .* ungreedy, otherwise it would only once fit the first and the last bracket as regexps are greedy by default.

var source = "{example1}{example2}{example3}";
var count = source.match(/\{.*?\}/g).length;

+1 - I misread this as a generic example, he's actually looking for the { and } :)
