Make array from regex

I have this string:

{example1}{example2}{example3}

This is the regular expression to find these { anything in it }:

/\{.*?\}/g

Now I want to know how put them in an array so I can do a for in statement.

I want an array something like array("{example1}","{example2}","{example3}"); ?

var matches = '{example1}{example2}{example3}'.match(/\{.*?\}/g);
// ['{example1}', '{example2}', '{example3}']

See it here.

Also, you should probably use a for loop to iterate through the array. for in can have side effects, such as collecting more things to iterate through the prototype chain. You can use hasOwnProperty(), but a for loop is just that much easier.

For performance, you can also cache the length property prior to including it in the for condition.
