Good morning,

I would like to know if there is a specific function in javascript, which extracts from the message below only the value "141", after identifying the term "Temperatura.SaidaATM".

{ "d" : { "Temperature.ATM Output" : [141]

**Edit: The above package comes from sub MQTT in Json format.

The complete package is this below:

{"d":{"Temperature.ATM Output":[141]},"ts":"2021-12-18T13:28:34.964579"}

However I need to treat it to extract only the information between brackets "[xxx]", in the example above it is "141" but this value varies.

But I also need the quoted reference "Temperature.OutputATM".

Summing up: 1- The message "{"d":{"Temperature.OutputATM":[xxx]}"ts":"2021-12-18T13:28:34.964579"}" is received.

2- I need to extract the xxx from a javascript code

3- When reading "Temperatura.SaidaATM" in the message, return only what is in square brackets right after "[xxx]"

4- Final message return: xxx

Thank you in advance!
