Regex to get string 'word' from `({#word#})` in Nodejs

Question

How do I get string word from ({#word#}) using regex in Nodejs?

The regex I'm using right now is: /\\(({#[^)]+#})\\)/g It gives me string {#word#} from ({#word#}) .

How do I get the word out?

Answer 1

Use this regex:

/\(\{#(.*?)#\}\)/g

and grab the first capturing group match:

/\(\{#(.*?)#\})\)/g.exec("({#test#})")[1] === "test"

Capturing groups are expressions between parentheses in a regex that will save the part of the text that matches it. You can have multiple, but in this case we only need one.

The .*? is simple but not efficient, if you have a regex for word then use that instead.
