extract value from array

TJ

External API response is a single array with decimal value in it.

last: [31.8]

How do I extract the value to be able to use it for math operations after? The value is dynamic and pulling from external API.

Hey @TJ!

You can save the number by mapping to it using dot notation.

Assuming that the External API response is in the form of an object, like this:
{"last":[31.8]}

Here is what it would look like.

You can then use the variable number to perform mathematical operations.
