Make array from regex

Question

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}"); ?

If you've got an actual Array, you'd be much better off using a simple for loop rather than a for...in, which may give you more than you bargained for: all extensions to Array's prototype will be listed, as well as the items in the array. — Tim Down

You shouldn't be iterating arrays with for-in. Use a C-style for loop, preferably. — strager

Will this make an array such like array("{example1}","{example2}","{example3}"); ?

@zolex true. I like to at least link to w3schools instead of the straight documentation, as they have examples and the "try it now" feature.

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.
