I have a string as below

string = "my name is [name] and Birtday is [birthday]"

I want to get all the words inside the placeholders into an array. The following shows the array.

array = [ "name", "birthday" ]

I have the following code.

array = sting.match(/[^[\]]+(?=])/g)

But This also returns the below text as two arrays.

string = "[name]month]"
array = ["name", "month"] this should be array = ["name"]

Dmap

Use `/\[([^\][]*)]/g` and grab Group 1. – Wiktor Stribiżew Mar 18 '21 at 22:33
@WiktorStribiżew this copy text including square brackets. "[text]" – Dmap Mar 18 '21 at 23:10
I said "grab Group 1", see [the famous JS regex thread](https://stackoverflow.com/questions/432493/how-do-you-access-the-matched-groups-in-a-javascript-regular-expression). – Wiktor Stribiżew Mar 18 '21 at 23:25
