How to assign data received via websocket to an array?

Question

Node.js

I get lines like this

[2022-03-11 16:48:10.751|]}]}
[|2022-03-11 16:48:10.721]}]}
[2022-03-11 16:46:47.660]}]}   
[2022-03-11 16:48:10.700]}]}

While the connection is active, I get these lines. I need only these 4, how can I make a filter so that when receiving strings, it compares these identifiers - "401203106, 401203109, etc."? That is, if they are in a string, then you need to assign it to an array.
In fact, I receive messages from the server and they go separately. I understand that I need to stop the connection as soon as the necessary lines are in the array, I understand how to do this, but I just can’t figure out how to assign these lines to the array
