javascript - Get values inside double curly braces with regex

Question

From this string:

dfasd {{test}} asdhfj {{te{st2}} asdfasd {{te}st3}}

I would like to get the following substrings:

test, te{st2, te}st3

In other words I want keep everything inside double curly braces including single curly braces.

I can't use this pattern:

{{(.*)}}

because it matches the whole thing between first {{ and last }}:

test}} asdhfj {{te{st2}} asdfasd {{te}st3

I managed to get the first two with this regex pattern:

{{([^}]*)}}

Is there any way to get all three using regex?

Answer 1

Try {{(.*?)}}.

.*? means to do a lazy / non greedy search => as soon as }} matches, it will capture the found text and stop looking. Otherwise it will do a greedy search and therefore start with the first {{ and end with the very last }}.
